Answer:
y = 1/2 x -4
Step-by-step explanation:
When we have a point and a slope, we can use the point slope form of an equation
y-y1 = m(x-x1)
y--2 = 1/2(x-4)
y+2 = 1/2x -2
Subtract 2 from each side
y+2-2 = 1/2x -2-2
y = 1/2 x -4
This is in slope intercept form where is the slope is 1/2 and the y intercept is -4
