Answer:i feel like its most likely gonna be the last one
Step-by-step explanation:
Rate is used to compare values of the same unit. So, it is important to convert rates to the same units so that the units can cancel out.
Answer:
(x, y) = (-2, 7), (0, -1), (3, -13), (-1, 3)
Step-by-step explanation:
To fill in the y-values, you need to put the x-value in the equation and evaluate.
<u>for x=0</u>
y = -4(0) -1 = -1
<u>for x=-1</u>
y = -4(-1) -1 = 4 -1 = 3
__
To fill in the x-values, we can solve for x and then do as we did above.
y = -4x -1
y +1 = -4x . . . . add 1
-(y +1)/4 = x . . . divide by -4
<u>for y=7</u>
x = -(7 +1)/4 = -2
<u>for y=-13</u>
x = -(-13+1)/4 = -(-12/4) = 3
__
Then the table is ...
