Question

Please check my answers on equations!

Given two points on the line, input the equation of the line in standard form Ax + By = C. Reduce all fractional answers to lowest terms.

(7, -3), (4, -8)

My answer: 5x - 3y = 26

Given two points on the line, input the equation of the line in standard form Ax + By = C. Reduce all fractional answers to lowest terms.

(-8, 0), (1, 5)

My answer: 5x -9x = -40

Answer 1

Substituting back into your answer, \[(5*7)-(3*-3)\neq26 \]

Answer 2

For the second, \[(5*-8)-(9*0)=-40\], so it looks good there.

Answer 3

Okay, so instead of "equal" on #1, it does NOT equal, right?

Answer 4

Right, in other words, your equation doesn't match the first point.

Answer 5

Great, thank you!

Answer 6

You're welcome. :)
