Find the equation of the line (-4,-7) and (12,1)
ryzh [129]

Answer:

y = 1/2x -5  slope intercept form

y-1 = 1/2(x-12)  point slope form

Step-by-step explanation:

We can find the slope of this line by using

m = (y2-y1/(x2-x1)

  = (1--7)/ (12 --4)

 = (1+7)/(12+4)

 = 8/16

  = 1/2

We know the slope and a point, so we can use point slope form

y-y1 = m(x-x1)

y-1 = 1/2(x-12)

y-1 = 1/2 x -6

Add 1 to each side

y-1+1 = 1/2x -6+1

y = 1/2x -5

This is in slope intercept form
