Question

graph 8x − 7y = 56

Answer 1

need some help can anyone help

Answer 2

solve for x by adding 7y to both sides then dividing both sides by 8 to isolate x.

Answer 3

or solve for y first by subtracting 8x from both sides then dividing both sides by -7 to isolate y

Answer 4

but it looks like both x and y = 1

Answer 5

would have to check to see if that were true

Answer 6

8x − 7y = 56

Little known "Intercept Form" is amazing. Divide by 56.

\(\dfrac{x}{7} + \dfrac{y}{-8} = 1\)

The intercepts are now staring at you. (7,0) and (0,-8)
