Idont know what im doing! explain your 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
