Equations of Lines

Find the slope of the line that passes through the points (2, 4) and (6, 12)

• 1/2
• -1/2
• 2
• -2

Find the slope of the line.

• -5/4
• 5/4
• -4/5
• 4/5

What is the equation of the line in slope-intercept form that goes through (2,1) and (4, 5)?

• y = 2x + 3

• y = -2x - 3

• y = -2x + 3

• y = 2x - 3

What is the equation of the line that goes through (3,4) and (9,-2)?  Use slope-intercept form.

• y = x -7
• y = 3x + 7
• y = x + 7
• y = -x + 7

.Write the equation of the line where m = -1 and passes through the point (-2, 4)
(y = mx + b)

• x = -2
• y = 4x - 2
• b = 2
• y = -1x + 2
