The equation of a line can be written in a format called "point slope form". Equations in this form look like y - y1= m(x - x1). In this formula (x1,y1) is any point on the line, m is the slope, x is the input (or dependent variable) and y is the output or dependent variable. Using this, and a given slope and point, you can construct the equation for a line.
The y-intercept is the point where a line crosses the y-axis. You don't know where on the y-axis, but you know that the x-value of any point of the y-axis is 0. Therefore, you can solve for the y-intercept bus substituting 0 for x and solving for y.

Find the equation of the line in slope intercept form slope 2 y-intercept -8?
The slope intercept form is y=mx+b where m is the slope and b is the y intercept y=2x-8.
How do you find the slope and y intercept of y equals mx plus b?
The value of m is the slope and the value of b is the y intercept.
What does the b represent in the slope intercept formula?
The slope-intercept formula for a line is y = mx + b, where m represents the slope of the line and b represents the y-intercept. This is due to the fact that when x = 0, y = b. This means the point (0,b) is on the line and is the y-intercept.
Find the equation when slope is -5 and y intercept is 7?
y=-5x+7 y=mx+b m= slope b= y-intercept
What is the difference between the slope and the y-intercept?
The slope is the value of m in which you "rise and run" point units The Y-intercept is the value in which X is zero
How do you find the y intercept in slope intercept form if the slope is 2 and the equation y equals 2x plus b help me please?
y = 2x + b to find y-intercept, you should know one point. you put the point into x and y. and you can find y-intercept. if you are still confused, i want you to follow the related link that explains the concept of slope intercept form very clearly.
What is point intercept form?
Point slope? y=mx+b M being the slope, and b being the y-intercept.
Formula for slope intercept?
You have to find the slope and y-intercept first.
Find the equation of the line in slope intercept form slope 2 y-intercept -8?
The slope intercept form is y=mx+b where m is the slope and b is the y intercept y=2x-8.
How would you find the equation of a line if you were given the slope and the y-intercept?
y = {slope}x + {y intercept}
How do you find slope intercept form?
the formula for slope-intercept form is y=mx+b. in the equation mx is the slope and b is the y-intercept.
Table to Linear Equation?
You get the linear equation from a table by: Seeing the difference between the y coordinates and that should give you slope. Then find the point where x = 0 and at that point the y coordinate associated with the x is the y intercept and at the point where y = 0 the x coordinate associated is the x intercept. apply the y intercept and slope to the equation y = mx + c with m being the slope and c being the y intercept
What is point slope form and slope intercept form?
y=mx+b is slope-intercept form y - y1 = m(x - x1) is point-slope form Used in algebra based math. On a graph; m is the slope b is the y-intercept x and y represent points
How do you find the slope and the y-intercept of each line?
y=Mx + b m = slope b= y-intercept
What is a line in slope-intercept form?
A line in slope-intercept form is: y = mx + b m is the slope of the line, and b is the y-intercept. To find the slope, find any two coordinates, and divide the difference in y-values by the difference in x-values; to find the y-intercept, find the value of y where x = 0.
Find the slope and y intercept of y -2?
y-2 +2 y=2 slope is undefined y intercept is 2
Does the value of the y-intercept depend on the slope of the line?
If you're given an existing point and the slope of the line, then yes - the y-intercept depends on the slope.
