# How do you write the equation of a line in slope intercept, point slope and standard form given Point: (5,-8) and is parallel to y=9x+4?

##### 1 Answer

Slope intercept form of the equation is

#### Explanation:

Lines that are parallel have the same slope. Knowing this, the slope is

Slope intercept form:

First plug in the slope:

Next we have to solve for

Now that we know b, we can plug it in to the slope intercept form, giving us

Point slope form:

Plug in the slope, which is

Plug the point that is given,

Simplify, giving you the final answer for point slope form:

Finally, standard form which is

To get standard form we can use slope intercept form which we know is

Subtract
