Keith_Richards [23]

Answer:

The slope of RT is: m = 1

Step-by-step explanation:

Given

R(-3, 1)

T(2, 6)

Determining the slope between (-3, 1) and (2, 6)

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(-3,\:1\right),\:\left(x_2,\:y_2\right)=\left(2,\:6\right)$

$m=\frac{6-1}{2-\left(-3\right)}$

Refine

$m=1$

Therefore, the slope of RT is: m = 1
