The slope of the line that goes through two points (x_1, y_1) and (x_2, y_2) is:

\dfrac{y_1-y_2}{x_1-x_2}

The two points we are given is (7,9) and (2,12). Substitute these values into the formula for the slope

=\dfrac{12-9}{2-7}

Simplify

=\dfrac{3}{-5}

Simplify again

=-\dfrac{3}{5}

This should be your answer. Let me know if you need any clarifications, thanks!

nika2105 [10]

Answer:

-31/6

Step-by-step explanation:

77+2(3x-5)=8-3(2x+1)

77+6x-10=8-6x-3

77-10+6x=8-3-6x

67+6x=5-6x

67+6x-(-6x)=5

67+6x+6x=5

67+12x=5

12x=5-67

12x=-62

x=-62/12

simplify

x=-31/6
