Algebra 1 Quiz - Section's 5.6 - 5.8

Graph each line given the slope and y-intercept.

Slope = -3, y-intercept = 5

Graph each line given the slope and y-intercept.

slope = -1, y-intercept = -6

Write each equation in slope-intercept form:

2x + y = 5

Write each equation in slope-intercept form:

2x - 6y = 6

• y = -2x + 1

• y = 2x + 1

• y = -2x +6

Write each equation in slope-intercept form:

3x + y = 3x - 4

• y = 6x -4

• y = -6x - 4

• y = -4

• y is undefined

At a chili cook-off, people pay a $3.00 entrance fee and $0.50 for each bowl of chili they taste. The graph shows the total cost per person as a function of the number of bowls of chili tasted.

Write a rule that gives the total cost per person as a function of the number of bowls of chili tasted.

• y = $3.00(x) + $0.50

• y = $3.00 (x) - $0.50

• y = $0.50(x) + $3.00

• y = $0.50(x) - $3.00

Entertainment At a chili cook-off, people pay a $3.00 entrance fee and $0.50 for each bowl of chili they taste. The graph shows the total cost per person as a function of the number of bowls of chili tasted.

Identify the slope and y-intercept of the function.

• Slope = 3

  y-intercept = 0.50

• Slope = 0.50

  y-intercept = 3

• Slope = -3

  y-intercept = -0.50

• Slope = -0.50

  y-intercept = -3

Graph the line with the given slope that contains the given point.

slope = -3, Point (0,3)
