Question

What is the slope-intercept form of the function that contains the point (3, 4) and has a slope of 2?

Answer 1

the slope is 2, so y=mx+b. m=slope.
y=2x+b.
The b is the y-coordinate of the point (0,b), where the line crosses the y-axis.

Answer 2

just plug in the point to the equation y=mx+b

4= (2)(3)+b
b= 4-6
b= -2

the slope intercept form is y=2x-2
