Answer:
Y=4x-27
Step-by-step explanation:
Parallel lines have the same gradient therefore it's-4
Y-5/X--8 =-4
Y-5=-4(x+8)
Y-5=-4x+-32
Y=-4x-32+5
Y=4x-27
First we put 7 in the place of y, after that subtract 7 from both sides, the answer is -2.
x + y= 5 y = 7
x+ 7=5
x= 5-7
x = -2
Answer:
No
Step-by-step explanation:
When we graph the points we can see that (3, 5) makes it not a linear fuction.
