$\frac{7.14}{42}=\frac{x}{63}$

Step 2

solve for x

$\begin{gathered} \frac{7.14}{42}=\frac{x}{63} \\ 63\cdot7.14=42x \\ x=\frac{63\cdot7.14}{42} \\ x=\frac{449.82}{42} \\ x=10.71 \\ \end{gathered}$

Y−3=5(x−2) FIND THE SLOPE PF THE LINE ASAP PLS

adelina 88 [10]

Slope is 5

Step-by-step explanation:

Step 1: The equation of the line is y - 3 = 5(x - 2). Find the slope.

y - 3 = 5x - 10

Slope intercept form is y = mx + b, where m is the slope.

y = 5x - 10 + 3

y = 5x - 7

m = 5
