Steps to Rewriting from Standard Form to Slope-Intercept Form
Move the x-term to the right side using opposite
Divide every term by the coefficient (number in front) of y
Answer will look like: y = mx + b
3
Subtract 6x (the whole term) and divide every term by 2
4
Rewrite 3x - 5y = 10 like y = mx+b
First move 3x to the right side by doing opposite (add -3x)
5
Open Ended
Add -3x to both sides of 3x - 5y = 10.
What does it look like?
6
Rewrite 3x - 5y = 10 like y = mx+b
First move 3x to the right side by doing opposite (add -3x)
-5y = -3x + 10
7
Rewrite 3x - 5y = 10 like y = mx+b
First move 3x to the right side by doing opposite (add -3x)
-5y = -3x + 10
Then divide EVERY term by -5
8
Rewrite 3x - 5y = 10 like y = mx+b
First move 3x to the right side by doing opposite (add -3x)
-5y = -3x + 10
Then divide EVERY term by -5
-5/-5 y = -3/-5 x + 10/-5
9
Rewrite 3x - 5y = 10 like y = mx+b
First move 3x to the right side by doing opposite (add -3x)
-5y = -3x + 10
Then divide EVERY term by -5
-5/-5 y = -3/-5 x + 10/-5
Then simplify the fractions
10
Open Ended
What does it look like after you simplify:
-5/-5 y = -3/-5 x + 10/-5 ?
11
Rewrite 3x - 5y = 10 like y = mx+b
First move 3x to the right side by doing opposite (add -3x)
-5y = -3x + 10
Then divide EVERY term by -5
-5/-5 y = -3/-5 x + 10/-5
Then simplify the fractions
y = 3/5x - 2

Rewrite 3x - 5y = 10 like y = mx+b
First move 3x to the right side by doing opposite (add -3x)
-5y = -3x + 10
Then divide EVERY term by -5
-5/-5 y = -3/-5 x + 10/-5
Then simplify the fractions
y = 3/5x - 2
Slope is 3/5 and the y-intercept is -2
15
Multiple Choice
Which equation is 3x + 2y = 8 in slope-intercept form?
y=23x +4
y=−23x +4
y=3x +4
y=−3x+4
16
Open Ended
