Linear Equations

Which of these represents point-slope form of a linear equation?

• y - y₁ = m(x - x₁)
• Ax + By = C
• y = mx + b

Select all of the following equations in point-slope form.

• y - 2 = 5(x - 2)

• 3x + 2y = 12

• y + 2 = 1/4(x + 4)

• y = 4x + 6

• 2y = 5x - 7

Write the equation for the line in slope-intercept form.

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

Write the equation in point-slope form of the line that passes through the given point and has the given slope.
(4, -7); m = -1/4

• y + 7 = -1/4(x - 4)
• y - 4 = -1/4(x + 7)
• y + 7 = 4(x - 4)
• y - 7 = -1/4(x - 4)

Which is the graph of y= -x - 3?

• A

• B

• C

• D

Write the equation that created this table.

• y = 3x

• y = 4x + 3

• y = 3x + 4

• y = 8x + 3

Find the slope and y-intercept of the following:

y = -8x + 13

• slope = -8/13, y-intercept = 1
• slope = -8, y-intercept = 13
• slope = 8/13, y -intercept = -8
• slope = 13, y-intercept = -8

Give the x-intercept
3x + 8y = 24

• (8, 0)
• (0, 8)
• (3, 0)
• (0, 3)

What is the y-intercept in the equation x + 2y = 4

• (0, 0)
• (0, 2)
• (4, 0)
• (2, 0)

Write an equation in point-slope form of the line that passes through the given points: ( - 3, - 2), (5, 3)

• y - 2 = 5/8 (x - 3)

• y + 2 = 5/8 (x + 3)

• y + 3 = 5/8 (x + 2)

• y - 3 = 5/8 (x - 2)
