Question

change all of the following equations into slope- intercept form.
2x - 5y ≥ -10
x - y ≥ 3
2x - y < -4
x + 2y ≥ -8

Answer 1

slope intercept form is y = mx + b

1. 2x - 5y >= -10
subtract 2x from both sides
-5y >= -2x - 10
Now divide both sides by -5 but remember in an inequality, when dividing by a negative, change the inequality sign
y <= -2/5x - 10/-5
y <= -2/5x + 2
do you understand how I did this one ?

Answer 2

oops....I made a mistake...let me fix it
-5y >= -2x - 10
divide by -5 and change inequality sign
y <= -2x/-5 - 10/-5
y <= 2/5x + 2

Answer 3

Solve for y
Do you have questions on solving the inequalities?
