Write the slope-intercept form of an equation for a line with y-intercept -5 and slope 2

• y = -2x +5

• y = -5x +2

• y = 2x - 5

• y = 2x + 5

What is the equation in Point-Slope Form of the line that passes through the point (1, -1) and has a slope of 4?

• y - 1 = 4 (x + 1)

• y - 4 = (x + 1)

• y + 1 = (x -1)

• y + 1 = 4 (x - 1)

Which equation represents the graphed line?

• y - 1 = -2 (x - 3)

• y - 1 = -2 (x + 3)

• y + 1 = -2 (x - 3)

• y + 1 = -2 (x + 3)

Which statement about the lines below is true?

4 y = -16 and 3x = 27 (Select all that apply)

• Line 4y = - 16 is horizontal

• Line 3x = 27 is vertical

• For both lines, all points on the line have an x and a y coordinate

• For either line, one of the coordinates of all the points is always the same value.

Which of the following is the equation of a line that is perpendicular to the graph of y = 2/5 x - 1

• y = 2/5 x - 4

• y = -5/2 x - 4

• y = -2/5 x - 4

• y = 5/2 x - 4

The Glee Club has $90 to spend on pens and pencils. Each pen costs $0.75 and each pencil costs $0.15. Let x represent the number of pens, and let y represent the number of pencils. Which equation describes the number of pens and pencils that the glee club can buy?

• 15x + 75y = 90

• .75x + .15y =90

• .15x + .75y = 90

• 90x + 15y = 75
