Find the value of r so the line passes through (r,-2) and (-7,-1) has a slope of m=-1/4

The value of "r" is -3 so the line passes through (r,-2) and (-7,-1) has a slope of m = -1/4

Given that line passes through (r, -2) and (-7, -1) has a slope of

To find: value of r

The slope of line passing through two points and is given as:

Here given that slope

Substituting the values in above formula, we get

Thus the value of "r" is -3

d

step-by-step explanation:

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
