Question

Find the slope and y-intercept of the line 18x+4y=112

Answer 1

y-intercept is y= -4.5+28 slope is 4.5

Explanation:

18x+4y=112

-18x -18x

4y=112-18x

-----------------

4

y= -4.5x+28

Answer 2

Answer: The slope is m=-9/2, and the y-intercept form

Explanation:

Rewrite in Slope-intercept form: y=mx+b

Subtract 18x from both sides of the equation.

4y = 112-18x

divide each term by 4 and simplify.

y= 28 - 9x/2

Reorder 28 and -9x/2.

y=-9x/2 +28

Find the values of m and b using the form y=mx+b.

Slope: -9/2

Y-intercept: 28
