What is the answer to these question?
Natali5045456 [20]

Answer:

2.  y = 7/2 x -2

3.   y = 3/4x-1

Step-by-step explanation:

points (0,-2)  (4,12)

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

slope = (12--2)/(4-0)

    = (12+2)/4

   = 14/4 = 7/2

the slope is 7/2 and the y intercept is -2

y = mx+b

y = 7/2 x -2


points (0,-1)  (4,2)

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

slope = (2--1)/(4-0)

    = (2+1)/4

   = 3/4

the slope is 3/4 and the y intercept is -1

y = mx+b

y = 3/4x-1
