Answer:

The slope is 3/2 and y-intercept is 5.

Explanation:

_______________________________________

The question states:

Find the slope and y-intercept of the line that is perpendicular to


y=-(2)/(3)x+5

and passes through the point (-6, -4)

_______________________________________

From functions, we know that if two lines, called line 1 and line 2, are perpendicular, then it is true that:


m_(1)* m_(2)=-1 \\ \\ \\ Where: \\ \\ m_(1): Slope \ of \ line \ 1 \\ \\ m_(2): Slope \ of \ line \ 2

If the given line is called line 1, then:


m_(1)=-(2)/(3)

Then:


m_(2)=-(1)/(m_(1)) \\ \\ m_(2)=-(1)/(-(2)/(3)) \\ \\ \boxed{m_(2)=(3)/(2)}

On the other hand, the y-intercept can be found as:


y=m_(2)x+b \\ \\ y=(3)/(2)x+b \\ \\ For \ (x,y)=(-6,-4) \\ \\ -4=(3)/(2)(-6)+b \\ \\ Solving \ for \ b: \\ \\ -4=-9+b \\ \\ b=9-4 \\ \\ \boxed{b=5}

Find the slope is 3/2 and y-intercept is 5.
