Question

What is the equation of a line that passes through points (0, 4) and (-4,-8)?​

Answer 1

3

Explanation:

Slope formula:

↓

`(Y_2-Y_1)/(X_2-X_1)=(Rise)/(Run)`

`((-8)-4)/((-4)-0)=(-12)/(-4)=(-12/-4)/(-4/-4)=(3)/(1)=3`

Therefore, the slope is 3 is the correct answer.

Answer 2

`\text{Hey there!}`

`\text{The slope formula is:}\frac{\bf{y_2\ - y_1}}{\bf{x_2\ - x_1}}`

`\bf{y_2 = -8}`

`\bf{y_1=4}`

`\bf{x_2=-4}`

`\bf{x_1=0}`

`\text{Your equation should look like this:}(-8 \ - 4)/(-4 \ - 0)`

`\text{Solve the numerator first (the top) then the denominator (the bottom) }`

`\text{-8 - 4 = -12}`

`(-12)/(-4 - 0)`

`-4 - 0=-4`

`(-12)/(-4) =\ ?`

`(-12/-4)/(-4/-4)=(3/1)/(1/1)=3`
