To write an equation from two data points, first identify the coordinates of the points, typically represented as (x₁, y₁) and (x₂, y₂). Calculate the slope (m) using the formula ( m = \frac{y₂ - y₁}{x₂ - x₁} ). Then, use the slope-intercept form ( y = mx + b ) to find the y-intercept (b) by substituting one of the points into the equation. Finally, write the complete equation of the line.
What else can I help you with?
Can you always write the equation of a line if you know one point on the line?
You cannot define a line with a single point (a single point only defines itself). You need two points to define a line (and therefore to write the equation for it).
Is the two points form equation the same as linear equation?
The equations are equivalent.
What equation models the data in the table if d number of days and c cost?
To determine the equation that models the data in the table with the variables ( d ) (number of days) and ( c ) (cost), you would typically look for a linear relationship of the form ( c = md + b ), where ( m ) is the slope and ( b ) is the y-intercept. By analyzing the data points in the table, you can calculate the slope using the change in cost divided by the change in days between two points. Once you have the slope, you can use one of the data points to solve for the y-intercept, allowing you to construct the complete linear equation.
What is a form of writing a linear eaquations when you are given 2 points?
To write the equation of a linear function given two points, you can use the slope-intercept form, (y = mx + b). First, calculate the slope (m) using the formula (m = \frac{y_2 - y_1}{x_2 - x_1}). Then, substitute one of the points into the equation to solve for the y-intercept (b). Finally, write the complete equation using the calculated slope and y-intercept.
How do you graph the linear equation 5x-4?
You write it as: y = 5x-4 Then you calculate a few sample points, plot them, and draw a straight line through them. Since the equation is linear, two points are enough, in theory, but it is usually recommended to plot a third point, as a verification.
Why can't you use two data points to write the equation of a line?
Actually, two separate points are enough to determine the line.
How can you write the equation for a linear function if you know only two ordered pairs for the functionDrag tiles to complete the explanation.?
the Equation of a Line Given That You Know Two Points it Passes Through.
What method can be used to write the equation of a line in slope-intercept form given two points?
You can follow the following steps. * First, you determine the slope between the two points. Just calculate delta-y / delta-x (that is, difference in y-coordinates, divided by the difference in x-coordinates, between the two points). * Next, you use the point-slope formula, to get an equation for the line. You can use any of the two points for this; each of the points will give you an equation that looks different, but the two equations are equivalent, if you do everything correctly. * Finally, solve the resulting equation for "y"; that will give you the equation in slope-intercept form.
Can you always write the equation of a line if you know one point on the line?
You cannot define a line with a single point (a single point only defines itself). You need two points to define a line (and therefore to write the equation for it).
Can you write the equation of a line with one point on the line?
No, you need either two points, one point and a slope, one point and a y-intercept, or a y-intercept an a slope. You can also write the equation of a line with an equation of another line but you would have to know if it is parallel or perpendicular.
Is the two points form equation the same as linear equation?
The equations are equivalent.
How do you write an equation given two points?
If there are given two points, (x1, y1) and (x2, y2), then you can write the equation of a line by finding the slope first [slope = m = (y2 - y1)/(x2 - x1)] and using one of the points in order to write the equation in the point-slope form such as(y - y1) = m(x - x1)y - y1 = mx - mx1y = mx - mx1 + y1y = mx + (y1 - mx1) the slope-intercept form, where m is the slope and (y1 - mx1) is the y-intercept.mx - y = mx1 - y1 the general form of the equation of the line.
Always use the vertex and at least points to graph each quadratic equation?
You should always use the vertex and at least two points to graph each quadratic equation. A good choice for two points are the intercepts of the quadratic equation.

How do you make a linear equation go through three points?
In general, a linear equation CANNOT be made to go through three points. That will only happen if the three points are collinear and in that case, the equation of the line will only require two points.
What is a solution of a linear equation in two variables?
The solution of a linear equation in two variable comprises the coordinates of all points on the straight line represented by the equation.
