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
