Find equation of te líne using function notation

*We will use three forms of linear equation:*

*(1) Standard form: Ax + By = C *

*(2) Slope-intercept form: y = mx +b *

*(3) Point-slope form: y - y _{1} = m(x - x_{1})*

**~~~~~~~**Parallel lines have the same slope. therefore, we have to convert given equation from standard to slope-intercept form:

7x + 8y = 88

- 7x - 7x

8y = -7x + 88

÷8 ÷8 ÷8

y = (-7/8) x + 11 ---> m = (-7/8)

To find the equation of the parallel line, let's use point-slope form:

y - 13 = (-7/8)(x - 8)

y - 13 = (-7/8) x + 7

+13 + 13

*y = (-7/8) x + 20*

*<---- final answer.*

**f(x) = (-7/8) x + 20**
