Writing Equations of Lines from Written Descriptions

Use the two ordered pairs (0, 1.8) and (5, 3.9) to write the equation of the line in slope-intercept form.

• y = 0.42x + 1.8

• y = 0.52x + 1.8

• y = 0.32x + 1.8

• y = 0.62x + 1.8

What is the y-intercept of the line with the equation y = 0.42x + 1.8?

What is the equation of the line passing through the points (-8,1) and (1,4) in slope-intercept form?

• y = 1/3x + 1

• y = 3x + 1

• y = -1/3x + 1

What is the standard form of the equation y = 1/3x - 2?

• -x + 3y = -6

• x - 3y = 6

• 3x - y = 6

• -x - 3y = 6

What is the x-intercept for the given graph?

• 1
• -2
• 2
• 1/2

True or false:
The x-intercept of a function ALWAYS occurs where y is equal to zero.

• True
• False
