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.
