Question

A line passes through the points A and B, whose coordinates are A(5, -5) and B(-10, -11). What is the equation of the line? The equation is given by Ax + Bx = C.

Answer 1

Answer:

Step-by-step explanation:

the instruction say put it in this form Ax +Bx = C  , but i'm sure they were meant to say this  Ax +By = C     note the  X and Y differences.  I'll use the latter form, b/c that's the  "standard" form

find the slope:

m = -11 - (-5) / -10-5

m = -11 + 5 / -15

m = -6 / -15

m = 2/5

y-(-5) = 2/5(x-5)

y + 5 = 2x/5 -2

y = $\frac{2}{5}$ x - 7

- $\frac{2}{5}$ x +y = -7

There you go, the right answer   :P
