Help plz my teacher won't help
lesantik [10]

Answer:

y = -3x + 9

Step-by-step explanation:

y = mx + b where m is the slope and b is the y intercept

The hypotenuse is on the same line as BC but twice as long.  So extend that line up and it will cross the y axis at (0,9).  9 will be your y intercept.

To find the slope start at C and count  up 9 and to the left 3 to get to B.

So the slope is rise/run or 9/(-3) = -3.

Final equation would be y = -3x + 9
