Question

Can someone help me with this (will give brainliest) please view the attached image

Answer 1

Answer:

rate: 4                             rate: -2

starting: 3                       starting: 30

y= -4x + 3                        y= -2x + 30

rate: 2                            rate: 6

starting: -4                     starting: 6

y= 2x -4                          y= 6x + 6

Step-by-step explanation:

$m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}$

^equation to find slope

To also find b, the starting value,  you need to take any point given and substitute it back into the equation with the slope.

However, these problems give you the y-int already [it is the point like (0,y)]

7-3/1-0 = 4/1

rate: 4

starting: 3

y= 4x + 3

28-30/1-0= -2/1

rate: -2

starting: 30

y= -2x + 30

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

rate: 2

starting: -4

y= 2x -4

6-0/1-0 = 6/1

rate: 6

starting: 6

y= 6x + 6
