Write an equation of the line that passes through (−2,1) and is parallel to the line y=3x−4. Equation: y=

y = 3x+7

Step-by-step explanation:

the slope of parallel lines are the same so the slope is 3

y-y1 = 3(x - x1)

y- 1 = 3(x- -2)

y-1 = 3x +6

y = 3x +7

so the rectangle is 80cm (area)

now to find the area of a triangle.

base times height.

4 times 8.

your answer is 96cm.

hope this .
