Question

I need help with 1, 3 and 5 help pls

Answer 1

Answer:

Step-by-step explanation:

1. y = 2x + 5

You input the values of x into the equation

y = 2(-2) +5

  = -4 + 5; y = 1

y = 2(-1) + 5; y = -2 + 5; y = 3

y = 2(0) + 5; y = 0 + 5; y = 5

y = 2(1) + 5; y = 2 + 5; y = 7

y = 2(2) + 5; y = 4 + 5; y = 9

5. y = x - 1

y = -2 -1; y = -3

y = -1 -1; y = -2

y = 0 - 1; y = -1

y = 1 - 1; y = 0

y = 2 -1; y = 1

Slot the numbers into the table of values

For example,

where x = -2 , y = -3

On the graph, where y is -3,  you trace it horizontally to the left. where x is -2 you trace it down. Where the lines meet you mark the point. Do the same for the rest.

Sorry, I can't solve no 3.
