Question

Use the given conditions to write an equation for the line in point-slope form and in slope-intercept form.

Passing through (-5, -7) and parallel to the line whose equation is y = - 4x + 4

Write an equation for the line in point-slope form.

Write an equation for the line in slope-intercept form.

Answer 1

Point-Slope Form is y + 7 = - 4( x + 5)
Slope-Intercept Form is y = - 4x - 27

Parallel equations have the same slope. The point-slope formula is basically y minus the given y-coordinate of the ordered pair, set equal to the slope being distributed to x minus the given x-coordinate. (If that explanation was complicated, you can just google the formula.) In order to find the slope-intercept form, you can use the point slope form and plug in zero for x to find the y-value that would be your y-intercept.
