Question

Find slope of the graph 9x-3y=15

Answer 1

Step-by-step explanation

• Convert the equation into slope-intercept form.

`y = mx + b`

where m = slope and b = y-intercept.

What we have to do is to make the y-term as the subject of equation.

`9x - 3y = 15 \\ 9x - 15 = 3y \\ (9x - 15)/(3) = y`

• Simplify

`(9x)/(3) - (15)/(3) = y \\ 3x - 5 = y \\ y = 3x - 5`

From y = mx+b, the slope is 3.

Answer

`\large \boxed {slope = 3}`
