From here we just use the point (-6,-8) and slope -8 to write the equation.
Explanation:
The equation of line:
y=mx+c
we have y=-8 x=-6 and m=-8 , so we need to find c.
Equation is y=-8x-56
if you would like to know how to find y in point (-7,y) the solution is below, but you don't need it for this question.
The slope or gradient has this formula when two points are given:
In this case we have the points (-6,-8) and (-7,y) and m=-8.
We use the formula:
