Warm-Up on Slopes of Lines

Find the slope:

• 3/4
• 4/3
• -3/4
• -4/3

Find the slope of the line that passes through:
(6,7) and (4,2)

• 2/5
• -5/2
• 5/2
• -1/2

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)

What are the x- and y -intercepts on this graph?

• (0,5), (0,5)
• (5,0), (5,0)
• (5,0), (0,5)
• (0,0), (5,0)

What is the y-intercept of the line graphed?

• 3
• 0
• It doesn't have one
• 2
