When you graph the equation and then plot the point you can see when in the equation what 2 is equal to. In this case it’s (2,12) so that means there is a 4 difference in the y-intercept since it’s parallel and the point is under the equation line you subtract 4 from the original equation y-intercept which gives you -2 . Then you plug it into the equation . The slope stays the same . 5x but then the new y-intercept is -2
y = 5x-2
#18. C. 1&3
This is be cause when you simplify to y=.. for 4y=3x and 8y=6x, they both turn out to be y=3/4x. The constant of proportionality is 3/4 because both equations simplify to have that as a constant.
#19. D
Kathy can add less than or equal to 7 books to her suitcase.
To cross off the first two choices(A&B), you input a number above 7 and then multiply it by 1 3/4 . Add it to 37 1/2 and it will be more than 50, meaning it will not fit since the suitcase can’t have more than 50 pounds in it.
To cross off C, you would multiply 1 3/4 by 7 and get 12.25. Add 12.25 to 37 1/2 and you will get 49.75 . This result would mean that you can have less than 7 books or just 7 books, leaving the answer to be D.
Answer: step 4 because you have to divide it not subtract it
Step-by-step explanation:
I believe the answer is
(x,y)-> (x+9,y-12)
Answer:
y=1/2 x -2 is the perpendicular line equation
Step-by-step explanation:
y=1/2 x + b
solving for b:
-3=-1 +b
b==- 3+1 = -2
