View the lane below and calculate the slope<br> by using the slope formula

velikii [3]

Answer:

slope = 4

Step-by-step explanation:

Calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (3, 12) ← 2 points on the line

m = $\frac{12-0}{3-0}$ = $\frac{12}{3}$ = 4

Kazeer [188]

Answer:

FC = 27, QC = 18

Step-by-step explanation:

The centroid Q is $\frac{1}{3}$ the way along CF , therefore, QF is half as long as CQ

Given FQ = 9, then

QC = 2 × 9 = 18

FC = FQ + QC = 9 + 18 = 27
