Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.

Rise is a vertical line from 0 to 4

Run is a horizontal line from 0 to 4

Slope of a line is called the gradient.

Additional information:

Gradient =rise/run

= 4/4

= 1

Y=mx +c

Y=1x +4

Y= x+4

But the slope show a negative correlation, so gradient will be negative & it's y = - x + 4.

BTW the rise and run could also be from 4 on the y-axis and down to the 4 on the x-axis.

So, there is two possible triangles you could make.

As a result, the rise is a straight line going up or down ( vertical ) and the run is a straight line going across from left to right (horizontal).

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

it would be 6xy and -16xy.
