Carey correctly graphs a linear function. The slope of the function is –1. The y-intercept is 3. Which is Carey’s graph?
On a coordinate plane, a line goes through points (0, 3) and (3, 0).
On a coordinate plane, a line goes through points (negative 3, 0) and (0, 3).
On a coordinate plane, a line goes through points (0, negative 1) and (1, 2).
On a coordinate plane, a line goes through points (negative 1, 2) and (0, negative 1).
The correct graph is: On a coordinate plane, a line goes through points (0, 3) and (3, 0).
What is the slope, m, and y-intercept for the line that is plotted on the grid below?
On a coordinate plane, a line goes through points (0, 4) and (negative 2, 0).
m = One-half, (0, –2)
m = One-half, (0, 4)
m = 2, (0, –2)
m = 2, (0, 4)
m = 2, (0, 4)
Mrs. Jacobson asked her students to write a word problem that describes the graph below.
A graph has days on the x-axis and money on the y-axis. A line goes through points (0, 8) and (4, 0).
Which word problem accurately describes the graph?
Jamie has $8, and she pays $2 per day to ride the bus.
Melinda has $4 and earns $2 allowance per day doing chores.
Carrina has $8, and she earns $2 per day babysitting.
Louise has $4, and she pays $2 per day for school lunch.
Jamie has $8, and she pays $2 per day to ride the bus.
The estimated total cost, y, of a child’s toy is partially based on the number of batteries used, x. The cost of one battery is $0.75. The toy itself costs $12. Which equation represents the situation?
y = 12x + 0.75
y = 0.75x + 12
y = 12x – 0.75
y = 0.75x – 12
y = 0.75x + 12
The slope of a line is 2. The y-intercept of the line is –6. Which statements accurately describe how to graph the function?
Locate the ordered pair (0, –6). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points.
Locate the ordered pair (0, –6). From that point on the graph, move up 2, left 1 to locate the next ordered pair on the line. Draw a line through the two points.
Locate the ordered pair (–6, 0). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points.
Locate the ordered pair (–6, 0). From that point on the graph, move up 2, left 1 to locate the next ordered pair on the line. Draw a line through the two points.
Locate the ordered pair (0, –6). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points.
Which linear equation has a slope of 3 and a y-intercept of –2?
y = 3x + 2
y = 3x – 2
y = –2x + 3
y = –2x – 3
