Question

What is the equation for the slope intercept form

Answer 1

The slope-intercept form is

y = mx + b,

where m = slope, and b = y-intercept

Now we get the y-intercept and the slope from the graph.

The y-intercept, b, is 4.

To find the slope, start at (-2, 0). Go up 4 and right 2 to point (0, 2). That is a rise of 4 and a run of 2.

m = slope = rise/run = 4/2 = 2

Equation:

y = mx + b

y = 2x + 4

Answer: y = 2x + 4
