Question

10. Which of the following is the equation of a line that passes through (-2,-1) and (-4,-3)?​

Answer 1

The slope is 1.

Explanation:

SLOPE FORMULA:

`\longrightarrow \displaystyle \mathsf{(y_2-y_1)/(x_2-x_1)=(rise)/(run)  }`

Y₂=(-3)

Y₁=(-1)

X₂=(-4)

X₁=(-2)

Solve.

`\displaystyle \mathsf{((-3)-(-1))/((-4)-(-2))=(-2)/(-2)=\boxed{\mathsf{1}}  }`

As a result, the slope is 1, which is our answer.

Answer 2

Let m = slope

m = (-3 -(-1))/(-4-(-2))

m = (-3 + 1)/(-4 + 2)

m = -2/-2

m = 1

Use the slope, one of the points given and the point-slope formula to find your equation.
