Question

Rewrite the following equation in standard form.

y = –10x + 5


Hint: The standard form of a linear equation is Ax + By = C where A and B are not both zero, and A, B, and C are integers whose GCF is 1.

Answer 1

Start with y = −10x + 5. Add 10x to both sides:

10x + y = 5

This is already in standard form Ax + By = C (A = 10, B = 1, C = 5) and the GCF of 10, 1, 5 is 1.
