In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

point1 (-5 , -5) x1 = - 5 y1 = - 5

point2 (-2 , 1) x2 = -2 y2 = 1

equation of the line = ?

Step 02:

slope formula


m\text{ = }(y2-y1)/(x2-x1)
m\text{ = }(1-(-5))/(-2-(-5))=(1+5)/(-2+5)=(6)/(3)=2

point-slope form of the line

(y - y1) = m (x - x1)

(y - (-5)) = 2 (x - (-5))

y + 5 = 2 (x + 5)

y + 5 = 2x + 10

y = 2x + 10 - 5

y = 2x + 5

The answer is:

The equation of the line is y = 2x + 5
