What is the slope, m, of the line through (-7, -2) and (-6, 7)?

Nataliya [291]

Answer:

Slope = 9

Step-by-step explanation:

(-7 , -2) ; x₁ = -7 and y₁ = -2

(-6 , 7) ; x₂ = -6 and y₂ = 7

Slope = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$=\frac{7-[-2]}{-6-[-7]}\\\\=\frac{7+2}{-6+7}\\\\=\frac{9}{1}\\\\= 9$

250 miles is 1 320 000 feet.

A penny is 0.005 feet tall.

You'd need 1 320 000 / 0.005 = 264 000 000 pennies to make a stack that high
