First, find the y-intercept of the line y=-2x+7. When x=0 you have that y=-2·0+7, y=7, then point (0,7) is the y-intercept.
When you rotate this line 90° clockwise about the origin, then point (0,7) will be placed on the x-axis in positive x-direction. Rotation preserves the distances, then the coordinates of the image are (7,0).
Answer: correct choice is D.
15+8x=2x+7-5x
Subtract 8x from both sides.
15=2x+7-5x-8x
Combine like terms.
15=-11x+7
Subtract 7 from both sides.
8=-11x
Divide -11 from both sides.
.73=x
Your answer is .72
