The points (-2, 4) and (1,r) lie on a line with slope 3. Find the missing coordinate r.

Answers

Answer 1
Answer:

Answer:

-9

Step-by-step explanation:

Slope = (y2 - y1)/(x2 - x1)

 (r - 11)/(4 - (-1)) = (r - 11)/5

So, (r - 11)/5 = -4

r - 11 = -20

r = -9

What are the solutions to the equation x^2-8x=24

Muriel says she has written a system of two linear equations that has an infinite number of solutions. One of the equations of the system is 3y = 2x – 9. Which could be the other equation?2y = x – 4.5
y = x – 3
6y = 6x – 27
y = x – 4.5

Answers

Answer: B

Step-by-step explanation: If you divide the 3 Y to get Y by itself, you will divide 3 on both sides. So 2X/3=2X/3 and -9/3=-3

So it will be Y=2X/3-3
