Answer:
16
Step-by-step explanation:
Area = perpendicular height * base
= DP * CB
= √[(2 - -1.2)^2 + (-5 - (-3.4)^ ] * √[(2 - 0)^2 + (3- -1)^2)]
= √(12.8.) * √(20)
= 16
=
Answer:

Answer:
3
Step-by-step explanation:
the slope of an equation (y=mx+b) is always "m", or the coefficient right infront of x. in this case, y=3x-7, 3=m, -7=b. m is the slope, so the slope is 3.
