Question

What is the equation in slope-intercept form that passes through the points (0,4) and (-2,0).

Answer 1

Answer:

slope intercept form is y=mx+b.  

The "m" in slope intercept form is the number that represents the slope of the line.  Think "m for movement" from any point to another.

The "b" in the equation is number that is the y-intercept.  The y-intercept is the y-value when x = 0, or where the line crosses the y-axis.  think "b for begin" on y-axis.

Substitute the numbers given in the problem into the form of the equation.  

m is 4

b is 2  

leave the x and the y because you need them so you can have a representation of all the points on the line.
