Question

A line with a slope of -2 passes through the point (-2,-3). What is the equation of this line?

Answer 1

m = -2

y = mx +c

-3= -2(-2) +c

-3 =4 + c , c = -7

Thus, equation is y = -2x-7

Answer 2

y = - 2x - 7

Explanation:

Step 1:

y = mx + b Slope Intercept Form

Step 2:

y = - 2x + b Input Slope

Step 3:

- 3 = - 2 ( - 2 ) + b Input x and y

Step 4:

- 3 = 4 + b Multiply

Step 5:

- 7 = b Subtract 4 on both sides

Answer:

y = - 2x - 7
