Algebra I Fundamentals - Unit 3: Functions. Slope-Intercept Form

Which of the following lines has a slope of -1/2?

x + 2y = 0

Write the equation for 5x + 2y = 3 in slope-intercept form.

y = -5/2x + 3/2

Write the equation 2x - 3y = 6 in slope-intercept form.

y = 2/3 x - 2

Using the slope and the y- intercept, graph the line represented by the following equation. Then select the correct graph. 2y + 4 = 0

(0, -2)

Using the slope and the y- intercept, graph the line represented by the following equation. Then select the correct graph. 3y = 2x - 6

(0, -2) and (3, 0)

Using the slope and the y- intercept, graph the line represented by the following equation. Then select the correct graph. x - y - 3 = 0

(0, -3) and (1, -2)

Using the slope and the y- intercept, graph the line represented by the following equation. Then select the correct graph. 2x - y + 4 = 0

(0, 5) and (1, 6)

What is the y-intercept of the line whose equation is y = 1/2 x - 3?

-3

Find the slope of the line whose equation is 5y = x - 3.

1/5

Which of the following describes how to graph the line whose equation is y = 2/3 x - 1?

Plot the point (0, -1), move up 2 and right 3, plot the point, and draw the line through these 2 points.
