Find the equation in slope-intercept form that describes a line through (4, 2) with
slope 1/2

y = 1/2 x

Step-by- Step explanation:

We have the slope of 1/2 and a point of (4,2)

We can use point slope form

y-y1 = m(x-x1)

y-2 = 1/2(x-4)

Distribute

y-2 = 1/2x -2

Add 2 to each side

y-2+2 = 1/2 x -2+2

y = 1/2 x

This is in slope intercept form

22

step-by-step explanation:

f(x) = y

f(-3) = -5
