1. Graphing Test Review
Algebra

2. Is the equation Linear?
xy = 7 x + 4 = y ¾ = y
No yes yes

3. Find the Slope
A(-1, 2), B(0, 5) C(4, -8), D(-3, -6)
m = m = -2/7

4. Given a point and a slope, fill into the equation in point-slope form.
m = 3, P(3, 4) m = -6, Q(-2, 3)
y – 4 = 3(x – 3) y – 3 = -6(x + 2)

5. Rearrange equations into standard form.
y = 2x y – 1 = 3( x – 2)
2x – y = x – y = 5

6. Given a slope and y-intercept fill into slope-intercept form.
m = -2, b = 3 m = ½, b = -1
y = -2x y = ½x - 1

7. Given two points, find the slope and slope-intercept equation.
A(3, 4), B(-3, 6) G(-1, -2), H(7, 8)
y = -1/3 x y = 5/4 x – 3/4

8. 3y = 6x + 9 2x + y = 4 y = 2x + 3 y = -2x + 4 m=2 b=3 m=-2 b=4
Rearrange equations into slope-intercept form. Identify slope and y-intercept from the equation.
3y = 6x x + y = 4
y = 2x y = -2x + 4
m=2 b= m=-2 b=4

9. Name the x and y intercepts.
3x – 2y = 6
x-intercept = (2,0)
y-intercept = (0,-3)

10. Use any method to graph the equation.
y =- ¾x + 2
-7x + 2y = 14

11. Identify the pair of lines as parallel, perpendicular or neither.
y = 2x + 3
2x + 4y = 7
perpendicular
