Answer:
Step-by-step explanation:
The area of a triangle is
and we have the base (12m) and we need to find the height. Using Pythagorean's Theorem:
That's the height that we will sub into the area formula:
Write the equation of a line that is perpendicular to the line y= (-1/5)x + 2 and has a y-intercept that is 5 units larger that

The slope (or average rate of change) formula is: 
. It is easy to remember as "slope is easy and fun, rise over run" where the y-values of the 2 points would be the "rise" and the x-values of the 2 points would be the "run" So with two points, you label one point as 
and the other as 
. Then you insert these points into the slope formula (m represents slope). So, 
where (-3,6) is x2 and y2 and (5,1) is x1 and y1. It would simplify to 
.
