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).

How do you write an equation in slope intercept form with a given point?
Slope Intercept form is meant for a line, so if you know the slope m in the equation y=mx+b then with a given point say (3,4) and say the slope of the line was 2 then the equation would read y=2x+4.
How the slope of a curved line at a point can be found?
The slope of a curved line at a point is the slope of the tangent to the curve at that point. If you know the equation of the curve and the curve is well behaved, you can find the derivative of the equation of the curve. The value of the derivative, at the point in question, is the slope of the curved line at that point.
What is the equation in slope-intercept form of the line that has a slope of -3 and contains the point 1 and1?
Assuming that the point is located at (1,1) then the equation is: y = -3x + 4 We know this by multiplying the slope by the x of the point given, and finding the difference between this value, and the y value of the point. 1 - (-3) is 4, hence the +4 in our equation.
How do you find the equation of a line without graphing?
There are a couple ways to determine the equation of a line without graphing. How to proceed depends on what you know about the line. Do you know a point, (x1, y1), and slope, m? Then use the point-slope formula, Do you know two points on the line, say (x1, y1) and (x2, y2)? Then use the two-point formula,
How do you know if an order pair is on the line of an equation?
Substitute the first of the ordered pair wherever x appears in the equation and the second value wherever you have y. Evaluate the equation. If it is true, then the point is on the line and if not, it is not.
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.

Define Volume percent and write the equation?
i dont know hahaha
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.?

What are the equation of the asymptotes for each graph?
that's simple an equation is settled of asymptotes so if you know the asymptotes... etc etc Need more help? write it
Write an equation for the scatter plot below. Then, use the equation to make your predictions?
Umm nobody can answer this question because we don't know what "the scatter plot below" is.

When writing a chemical equation what must be written first?
First write down what you know. Reactants go on the left, followed by an arrow, with products on the right. Balance the equation.
Why is it important to write down the main point of each paragraph?
You write down the main point so that your reader will know what it is. You also write it down so that you can be certain you have explained or supported the topic correctly.
