9x+2y=18

The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.

y=mx+b

Subtract 9x from both sides of the equation.

2y=18-9x

Divide each term by 2 and simplify.

Divide each term in 2y=18-9x by 2.

2y2=182+-9×2

Cancel the common factor of 2.

Cancel the common factor.

2y2=182+-9×2

Divide y by 1.

y=182+-9×2

y=182+-9×2

Simplify 182+-9×2.

Simplify each term.

Divide 18 by 2.

y=9+-9×2

Move the negative in front of the fraction.

y=9-9×2

y=9-9×2

Reorder 9 and -9×2.

y=-9×2+9

y=-9×2+9

y=-9×2+9

Rewrite in slope-intercept form.

y=-92x+9

y=-92x+9

Using the slope-intercept form, the slope is -92.

m=-92

Find the Slope 9x+2y=18
