Which equation represents the following graph?

• y = 3x + 2

• y = -2x + 3

• y = 2x + 3

• y = -3x + 2

Which of the following is in slope-intercept form?

• y=10x-7
• y-5=3(x-1)
• 5x-y=12
• 6x+2y-15=0

Find the slope between the points
(-4, 3) and (-4, -7)

• 5/4
• -10/8
• Zero
• Undefined

Solve for y
8x + 2y = -10

• y = -8x + 5
• y = -4x - 5
• y = -¹/₄ x - 10
• y = -¹/₄ x - 5

What is the slope a horizontal line?

• -1
• undefined
• 1
• 0

Write equation of the line containing (4,2) and (3,5)

in slope-intercept form.

• y = -3x + 14

• y = 3x - 4

• y = -3x + 4

• y = -3x + 10

Write the equation of the line that passes through the point (1, -1) and has a slope of -4.

• y - 1 = -4(x + 1)

• y + 1 = -4(x + 1)

• y + 1 = -4(x - 1)

• y - 1 = -4(x - 1)

A helicopter hovers 40 ft above the ground. Then the helicopter climbs at a rate of 21 ft/s. Write a rule that represents the helicopter’s height h above the ground as a function of time t. 

• h = 40t + 21
• h = 21t + 40
• h = -40t + 21
• h = -21t + 40

For the equation

y - 3 = 2(x + 4),

the line has a slope of 2 and contains what point?

• (-4, -3)

• (3, -4)

• (-3, -4)

• (-4, 3)

Write the equation in point-slope form of the line that passes through the given point and has the given slope:
 (-2, -1); m= -3

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