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:
^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
