Answer 1

`(59)/(11)`

Explanation:

The "b" value is when the x value is 0 (or the y intercept).

Lets first find the slope so we can find the y intercept.

Slope Formula:

`\frac{y_1-y_2} {x_2-x_1}`

Plug into the formula.

`(6-5)/(7--4)` (
`(1)/(11)`)

Slope is 1/11.

Now we can start forming a equation.

y = 1/11x + b

Slope of 1/11 means that every 11 gone right, 1 goes up. Lets use another formula to calculate.

`b = y_1 - mx_2`

Plug in.

`b = 5 - (1)/(11) (-4) \\b = 5-(-4)/(11)\\b = 5 + (4)/(11) \\b = (59)/(11)`
