0.10n - 0.60 + 0.05n = 2.10
0.15n = 2.70
n = 2.70/0.15
n = 18

What is the equation of a line going through points (-15,70) and (5,10)
andrey2020 [161]
Simple....

you have:

(-15,70) and (5,10)

Using-->>

\frac{  y_{1} -y_{2} }{ x_{1}-  x_{2} }

\frac{70-10}{-15-5} = \frac{60}{-20} = -3

Using y=mx+b...and any of the coordinates....

70= -3(-15)+b

70=45+b

70=45+b
-45  -45

25=b

y=-3x+25

Thus,your answer.
