Question 1190294: 15x+18y≥125
can you put that in slope-intercept form? because I don't know how to solve for y
thanks :> Found 2 solutions by math_tutor2020, Edwin McCravy:Answer by math_tutor2020(3817) (Show Source):
Then divide both sides by 18 to undo the multiplication on y
The entire time, the inequality sign stays the same. It only would flip if you multiplied or divided both sides by a negative number (which in this case didn't happen)
The inequality is now in slope intercept form
It's of the form
The boundary is
m = -5/6 is the slope
b = 125/18 is the y intercept
To graph this, you'll graph the boundary line . It's a solid boundary line and you'll shade above the boundary.
The solid boundary is due to the "or equal to" as part of the inequality sign.
Points on the boundary are part of the shaded solution set region.
Here's one exactly like it, only it has = not ≥
Oh crap, she did it for you!
Subtract the term in x by adding -16x
That's the slope intercept-form y = mx + b.
Here m = -4/5 and b = 27/4
That means the slope is and the y-intercept is .
