Find the slope based on these two points:

(18, -32) and (-7, 18)

What are the x and y-intercepts of the line described by the equation?

4x - 10y = 22

• x-intercept: 5.5

  y-intercept: -2.2

• x-intercept: 0.5

  y-intercept: 2.6

• x-intercept: 6.5

  y-intercept:-3.4

• x-intercept: 4.5

  y-intercept: -1.8

Graph the line given the slope and point given in the equation:

y - 4 = 5/2(x + 2)

Graph the following linear equation:

y = 2/3x - 9

Which equation represents the correct standard form for the equation:

23x + 17 = -8y - 4

• 23x + 17y = -4
• 8y + 23x = -17
• 23x + 8y = -21
• -23x + 8y = 21

What is the point-slope form of the line with a slope of 5/4 and the point (-3, 8)?

• y - 8 = (4/5)(x + 3)
• y - 8 = (5/4)(x - 3)
• y + 3 = (5/4)(x - 8)
• y - 8 = (5/4)(x + 3)

• (0, 0)

• (1, 3)

• (7, -3)

• (-4, -6)

• (-5, 2)

Bryce is buying notebooks and pens at an office supply store. Notebooks cost $4.73 and pens cost $2.29. He can spend up to $17 on these items.

Let x represent the number of notebooks. Let y represent the number of pens.
