Linear Equations and Graphs Mastery

Given two points (3, 7) and (5, 11), find the equation of the line in slope-intercept form.

• y = 2x + 1

• y = 2x + 3

• y = 2x - 1

• y = 2x + 5

If the slope of a line is 4 and it passes through the point (2, -3), what is the equation of the line?

• y = 4x - 11

• y = 4x + 5

• y = 4x - 8

• y = 4x + 8

Looking at the graph of a line, you see that it passes through the points (0, -2) and (4, 2). What is the slope of this line?

What is the equation of the line that has a slope of -3 and passes through the point (4, 2)?

• y = -3x + 14

• y = -3x + 12

• y = -3x + 10

• The slope is 5.

• The slope is 0.

• The y-intercept is 5.

• The x-intercept is 5.

If a line has a y-intercept of -4 and a slope of 1/2, what is the equation of the line?

• y = 1/2x - 4

• y = 2x - 4

• y = 1/2x + 4

• y = 2x + 4

On a graph, a line crosses the y-axis at (0, -7) and has a slope of 3. What is the equation of this line?

• y = 3x - 7

• y = -3x - 7

• y = 3x + 7

• y = -3x + 7
