Ok, so the changing aspect it the per hour. so for Naomi it would be 2x. she already has 16.5 . so her equation would be y=2x+16.5 . for Claire, the changing variable would be 4x. she already has 7.5 . her equation would be y=4x+7.5 . both equations are equal to the same variable, so you put them together to make 2x+16.5=4x+7.5 . first you would get rid of the x variables by subtacting the 2 on each side giving you 16.5=2x+7.5 . subract the 7.5 on each side and then divide by 2. then you will get your answer.
Answer:
(0,5)
Step-by-step explanation:
Perpendicular lines have slopes which are negative reciprocals of each other. The slope of the line y=1/2x + 6 is 1/2. The slope perpendicular to it is -2.
Using m=-2, substitute it and (4,-3) into the point slope form and simplify to find the y-intercept.
The equation is now in slope intercept form y=mx+b and b is the y-intercept. The y-intercept of y=-2x+5 is (0,5).
