Find that slope!
First step to solve
Graphing
100
What is the slope of this line?
y = 5x + 2
5
100
2x=10
Divide both sides by 2
100
Is this a positive or negative slope?
Negative
200
What is the slope of this line?
y = 2 - 3x
-3
200
4x - 1 = 15
Add 1 to both sides
200
What is the y-intercept of this line?
y = 2x - 5
-5
300
What is the slope of this line?
2
300
21 = 5+4x
Subtract 5 from both sides
300
What is the y-intercept?
3
400
What is the slope of this line?
1/2
400
4(x+2)=20
Distribute the 4

In slope-intercept form (y=mx+b), write the equation of a line with a slope of 2 and a y-intercept of -1.
y=2x-1
500
What is the slope of this line?
y-4=-6(x+2)
-6
500
3x + 2 + 4x = 20
Combine like terms (3x and 4x)
500
What would be the slope of a line PARALLEL to this line?
y=3x-7
