D is correct. To find the slope find the distance of the first y to the second (8) and the distacne of the first x and the second(4)

rise/run can define slope so  8/4 is your slope

The slope is 2 and the y intercept always has x=0. In the chart when x=0, y=-4

therefore your intercept is 0, -4 or just -4

Step-by-step explanation:

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:
