What would 2x + 3y = 1,470 be in slope intercept form and how do you get it
Flauer [41]

slope intercept formula is y = mx + b.

Isolate the y. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 2x from both sides

2x (-2x) + 3y = (-2x) + 1470

3y = -2x + 1470

Isolate the y. Divide 3 from both sides

(3y)/3 = (-2x + 1470)/3

y = (-2x + 1470)/3

Simplify

y = (-2/3)x + 490

y = (-2/3)x + 490 is your answer

hope this helps

marissa [1.9K]

Answer:

−x+−7

Step-by-step explanation:

Let's simplify step-by-step.

4x−6−(5x+1)

Distribute the Negative Sign:

=4x−6+−1(5x+1)

=4x+−6+−1(5x)+(−1)(1)

=4x+−6+−5x+−1

Combine Like Terms:

=4x+−6+−5x+−1

=(4x+−5x)+(−6+−1)

=−x+−7
