Freeman Write Equations of Lines

Write the equation of the line:
Slope = 3 and y-intercept 10

• y = 3x + 5
• y = 3x - 3
• y = 3x + 10
• y = 2x - 2

Find the slope from the table.

• -4
• 1
• 4
• -2

What is the slope a horizontal line?

• -1
• undefined
• 1
• 0

Write the equation of a line that contains the point (3, 5) and has a slope of 3 in slope-intercept form.

• y = 3x - 4
• y - 5 = 3(x-3)
• y = 3x + 14
• y + 5 = 3(x+3)

Which graph represents x = 2?

• A
• B
• C
• D

Which equation is parallel to:
y = 5/7x +2

• y = -7/5x +1
• y = 7/5x +4
• y = -5/7x -3
• y = 5/7x +5

Which equation is perpendicular to:
 y = -6x +2

• y = 6x +1
• y = -1/6x +4
• y = -6x +3
• y = 1/6x +5

y-intercept -3, x-intercept 7

• y = 3
• y= -3/7x - 3
• y = 3/7x +1
• y = 7

Horizontal line through (-3,8)

• x = 8
• y = 3
• x = -3
• y = 8

Vertical line through (6,-7)

• x = 6
• y = 6
• x = -7
• y = -7
