Answer:
y = 18x + 21
Step-by-step explanation:
Let x be the amount of hours of the renting and y the final cost
y = 18x + 21
In fact the final cost depends from the hours of the renting
The equation is already is slope intercept form where you can easily point out the gradient, or the slope, and the y intercept.
y=mx+b where m is the gradient, and b is the y intercept.
Since there is no m, the gradient is 1.
The y intercept had x=0 and y=b
b in this case is 6
the y intercept= (0,6)
Second one is a
im pretty sure
7x7=49 and 8x8=64
It’s might be D
