4x - 3 = -x - 13
4x + x = -13 + 3
5x = -10
x = -10/5
x = -2
y = 4x - 3
y = 4(-2) - 3
y = -8 - 3
y = -11
solution is (-2,-11)
Answer:
what is the question bro?
For this case, the first thing we must do is define variables.
m: number of times you cut the grass
d: amount of dollars you earn.
We now write the linear equation that models the problem:
d = 12m
The slope of the line is 12, which means that each time you cut the grass, you earn 12 dollars.
Answer:
an equation for the number of dollars, d, you earn when you mow the lawn m times is:
d = 12m
Answer:
The slope equals the rise divided by the run:
