Write the equation of the line that passes through the points (1, -7) and (-6, -9).
jek_recluse [69]

Answer:

y = 2/7 x - 51/7

Step-by-step explanation:

Equation of the line

(y-y1)/(y2-y1) = (x-x1)/(x2-x1)

(y-(-7)/(-9-(-7) = (x-1)/(-6-1)

(y+7)/-2 = (x-1)/-7

(-y-7)/2 = (-x+1)/7

-y-7 = -2/7 x + 2/7

-y = -2/7x +2/7 + 7

y = 2/7 x - 2/7 - 7

y = 2/7 x + (-2-49)/7

y = 2/7 x - 51/7

Solve the formula Ax+By = C for A.
jok3333 [9.3K]

Answer:

A = \frac{C - By}{x}

Step-by-step explanation:

Given

Ax + By = C

Required

Solve for A

The question implies that we make A the subject of the formula.

Start by subtracting By from both sides of the equation by x

Ax + By - By= C - By

Ax = C - By

Divide both sides by x

\frac{Ax}{x} = \frac{C - By}{x}

A = \frac{C - By}{x}

<em>Solved</em>
