Answer:

Step-by-step explanation:
The given equation is written in the form of y=mx+c (where m is the gradient and c is the y-intercept).
Thus, gradient of given equation= -⅔
The products of the gradient of perpendicular lines is -1.
(Gradient of line)(-⅔)= -1
Gradient of line

Hence, m=
.
Subst. m=
into the equation:

To find the value of c, substitute a pair of coordinates into the equation:
When x= -4, y= 2,

Thus, the equation of the line is
.

Answer:
Trapezoid
Step-by-step explanation:
So there's four sides on a trapezoid. The top and bottom ones are parallel. But they're not congruent. I don't think... Anyway, good luck.
