Assessment: Linear Equations

How would you write the equation with a slope of 4/5 and a y-intercept of -1

• y= -x + 4/5

• y= x + 4/5

• y= 4/5x - 1

• y= 2/5x + 4/5

This line has a __________ slope.

• Negative

• Positive

• Undefined

• No Slope

Find the slope  and y-intercept of:

2x - 3y = -12

• slope = 2/3, y-intercept = -12
• slope = -2/3, y-intercept = -3
• slope = 2/3, y-intercept = 4
• slope = -12, y-intercept = -3

Write the equation of the line.

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

Write the equation of the line.

• y = -1/3x - 2
• y = 1/3x - 2
• y = 3x - 2
• y = -3x - 2

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)

Write an equation  
m = 5 through (-1, -3)

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

Write the equation in point-slope form for the line that contains the points
(-2, -3), (4, 3)

• y - 3 = 1(x - 2)
• y + 3 = 1(x + 2)
• y -3 = -1(x + 2)
• y + 3 = -1(x - 2)

Write the equation in slope-intercept form for the line that contains the points
(3, -5) and (5, - 1)

• y = 2x + 11
• y = 2x + 1
• y = 2x - 1
• y = 2x - 11
