slope of 3x+3y=18 — step-by-step solution

⚠ 3x is read as the product 3*x: for a power, write 3^x‖3y is read as the product 3*y: for a power, write 3^y

⇥Let's solve in

ℝ

3 x + 3 y = 18

⇥

3 y = 18 - 3 x

⇥

y = \frac{18 - 3 x}{3}

⇥Solution found:

y = 6 - x

The slope-intercept form is

y = m x + b

: the slope is

-1

and the y-intercept is

6

▶Slope:

-1
