Question

Complete equation describing how X and Y are related.

Answer 1

`2`

Explanation:

Every time the x-value increases by 1, the y-value increases by 2. Therefore, the slope of the line must be equal to
`2/1=\boxed{2}` (rise/y-values over run/x-values). In slope-intercept form
`y=mx+b`,
`m` represents the slope of the line,
`b` represents the y-intercept, and
`(x,y)` represents any point the line passes through.

Since
`m` represents the slope of the line, the value of

While the question only asks for this value, it's good to note that the equation of the function is
`y=2x+7` (find 7 by substituting any ordered pair in the table with
`m=2`).

Answer 2

y = 2x + 7

Explanation:

y = mx + b

For every increase of 1 in x,

there is an increase of 2 in y

m = 2

When x is 0,

y is 7

b = 7

y = 2x + 7
