Answer:
y = 2x - 1
Step-by-step explanation:
The line passes through point (-7,-8)
The line is parallel to line whose equation is 2x - y = 6
Converting the equation of the second line into form y = mx + c;
2x - y = 6 is equal to y = 2x - 6 (the slope of this line is 2)
For parallel lines the value of their slopes is the same.
So our first line passes through point (-7,-8) and has a slope of 2
Taking another point (x,y) on the line;
Slope = Change in y ÷ change in x = = 2
y + 8 = 2x + 7
y = 2x + 7 - 8
y = 2x - 1

Step-by-step explanation:
First plot points A, B, C and D on the coordinate plane and connect them to get quadrilateral ABCD. Then plot the vertices E, F, G, H of the quadrilateral EFGH in each case.
For each of these cases there are attached diagrams
1 case - reflection acraoss the x-axis
2 case - translation 5 units down
3 case - reflection across the y-axis
4 case - translation 7 units right
