Answer 1

1. Output

2. Slope

3. y-intercept

4. y = 14

5. y = -3

6. y = -4

7. y = 12

8. y = 4

9. y = 5

10. y = 6

Explanation:

To solve problems 4-10, plug in the given values and simplify the equations.

4. y = -5(-2) + 4

y = 10 + 4

y = 14

5. y = 3(0) - 3

y = 0 - 3

y = -3

6. y = 2(4) - 12

y = 8 - 12

y = -4

7. y = 6(2)

y = 12

8. y = 3(1) + 1

y = 3 + 1

y = 4

9. y = -0.25(8) + 7

y = -2 + 7

y = 5

10. y = -3(-5) - 9

y = 15 - 9

y = 6
