Question

Complete the table.
x | y
-3 | 5
-2 | 9
-1 | 13
0 |
1 | 21

Answer 1

I have accidentally clicked enter. Please also send in an equation to match the data from the table.

Answer 2

The x column decrease by 1 each step.
What is the increase in the y column?

Answer 3

The increase in the y column is +4, but how can it be put into an equation that matches up?

Answer 4

I'm sorry, but I don't know about the equation. However, I'm sure a math tutor will help you later this evening.

Answer 5

Actually, for every <b>increase</b> of 1 in the x's we have an increase of 4 in the y's
so the slope is 4, thus:
y = 4x + b
so when x = 0, increase the previous y by 4 to get 17
which also makes it the y-intercept

Or, use two points (-3,5) and (-2,9)
slope = (9-4)/(-2 - (-3)) = 4
then using the point-slope form:
y - 5 = 4(x + 3)
y = 4x + 12 + 5
y = 4x + 17

so clearly: y = 4x + 13

check to see if the other points satisfy my equation, (they do)
