To find the slope and y-intercept, you can convert the linear equation into the form y = mx + b, where m is the slope and b is the intercept.
To do so, just simplify for y.
[tex]18x+4y=112[/tex]
[tex]4y=-18x+112[/tex]
[tex]y = - \frac{18}{4}x+28 [/tex]
So, the y-intercept is (0, 28) and the slope is 4.5.
Hope that helps!
