how do you solve for 2y-18x=-26

Answer 1

How do you solve for 2y - 18x = -26.

You have to know what you are solving for. There are two unknowns. Which are you solving for? Commonly, one solves for y because then you can turn the above equation into slope-intercept form. So, I will do that now. You solve by utilizing the INVERSE OPERATIONS and SIMPLIFYING until the variable is isolated (or by itself on one side of the equal sign)

2y - 18x = -26

ADD 18x to both sides (add is the inverse of subtraction)

2y = 18x - 26 (No simplification needed)

DIVIDE all terms by 2 (there are 3 terms: 2y, 18x, -26)

y = 9x - 13

This is in the SLOPE-INTERCEPT form: y = mx + b m = the slope b = y-intercept

So, if this equation is graphed, the line will cross the y-intercept at (0,-13)

and will slanted up to the right (positively) at a slope of 9/1
