## System of Linear Graphs - Sample Math Practice Problems

The math problems below can be generated by MathScore.com, a math practice program for schools and individual families. References to complexity and mode refer to the overall difficulty of the problems as they appear in the main program. In the main program, all problems are automatically graded and the difficulty adapts dynamically based on performance. Answers to these sample questions appear at the bottom of the page. This page does not grade your responses.

1

y = x + 1 Solution
"Eyeball" the graph for the intersection coordinates. You can also try plugging them into x and y in the original equations to make sure they make the two sides equal:
(3) = (2)/2 + 2
(3) = (2) + 1
2 Solution
"Eyeball" the graph for the intersection coordinates. You can also try plugging them into x and y in the original equations to make sure they make the two sides equal:
(-1) = -(2)/2
(-1) = 3(2)/2 + - 4

### Complexity=5

Solve using the graph. Answer in the form (x,y) -- using parentheses. For example: (-2,3)

1
y = - 5x + 8 Solution
"Eyeball" the graph for the intersection coordinates. You can also try plugging them into x and y in the original equations to make sure they make the two sides equal:
(3) = - 5(1) + 8
(3) = 5(1)/3 + 4/3
2 Solution
"Eyeball" the graph for the intersection coordinates. You can also try plugging them into x and y in the original equations to make sure they make the two sides equal:
(-5) = - 5(0)/4 + - 5
(-5) = -(0)/2 + - 5

### Complexity=10

Solve using the graph. Answer in the form (x,y) -- using parentheses. For example: (-2,3)

1 Solution
"Eyeball" the graph for the intersection coordinates. You can also try plugging them into x and y in the original equations to make sure they make the two sides equal:
(2) = 10(2)/3 + - 14/3
(2) = - 6(2)/5 + 22/5
2

y = - 2x + - 21 Solution
"Eyeball" the graph for the intersection coordinates. You can also try plugging them into x and y in the original equations to make sure they make the two sides equal:
(-7) = 4(-7)/5 + - 7/5
(-7) = - 2(-7) + - 21

### Complexity=13

Solve using the graph. Answer in the form (x,y) -- using parentheses. For example: (-2,3)

1 Solution
"Eyeball" the graph for the intersection coordinates. You can also try plugging them into x and y in the original equations to make sure they make the two sides equal:
(6) = - 2(-1)/13 + 76/13
(6) = - 5(-1)/6 + 31/6
2 Solution
"Eyeball" the graph for the intersection coordinates. You can also try plugging them into x and y in the original equations to make sure they make the two sides equal:
(8) = 2(-8)/13 + 120/13
(8) = - 3(-8)/5 + 16/5

### Complexity=14

Solve using the graph. Answer in the form (x,y) -- using parentheses. For example: (-2,3)

1

y = x + 2 Solution
"Eyeball" the graph for the intersection coordinates. You can also try plugging them into x and y in the original equations to make sure they make the two sides equal:
(7) = - 2(5)/3 + 31/3
(7) = (5) + 2
2

y = - 9x + 99 Solution
"Eyeball" the graph for the intersection coordinates. You can also try plugging them into x and y in the original equations to make sure they make the two sides equal:
(0) = -(11)/5 + 11/5
(0) = - 9(11) + 99

### Complexity=15

Solve using the graph. Answer in the form (x,y) -- using parentheses. For example: (-2,3)

1 Solution
