Review Lesson 5-3: Match the slopes m and y-intercepts b with their equations.

m = 1
m = -1
m = 6
b = 0
b = 4
b = -13

y = x + 4
y = 6x
y = -x - 13

Asemmisa {{asɛmmisaAhyɛnsode}}

2.

Review Lesson 2-5: Solve the equation for y.

y = \frac{z}{7x}

y = 7xz

y = \frac{7z}{x}

Asemmisa {{asɛmmisaAhyɛnsode}}

3.

Review Lesson 2-5: Solve the equation for y.

y = \frac{3b + 7}{a}

y = \frac{7b + 3}{a}

y = \frac{7b - 3}{a}

Asemmisa {{asɛmmisaAhyɛnsode}}

4.

Review Lesson 2-5: Solve the equation for y.

y = \frac{c}{6} - x

y = -\frac{c}{6} + x

y = 6c - x

5.

Vocabulary Review: Classify each equation based on its y-intercept.

y = 3x + 4
y = -3x + 2
y = 5x + 3
y = 4x - 3

Has a y-intercept of 3
Has a y-intercept other than 3

Asemmisa {{asɛmmisaAhyɛnsode}}

6.

Vocabulary Review: Categorize each equation based on whether or not it is in slope-intercept form.

y - 4 = 2(x + 7)
x + 3y + 11 = 0
y = 2x + 6
2x - y = 10

Slope-intercept form
NOT Slope-intercept form

7.

Vocabulary Review: Classify each statement based on whether or not it is true about the y-intercept of any graph.

occurs where x = 0 on the graph
occurs where y = 0 on the graph
occurs where the graph touches the x-axis

True of the y-intercept of any graph
NOT true of the y-intercept (of at least some graphs)
