Answer:
She forgot to add the zero when she multiplied 27 x 50
Step-by-step explanation:
If you need one ask me I can try my best to explain
3 + x/2 = 7
x = (7-3)*2 = 8 = the number
D is correct because you could put in a value for x and get a true value for y
exg
x=3
y=14(3)-9
y=42-9
y=33
Your answer would be -2.2
Y=Mx +c
M gradient so count how many squares per one line
C = y intercept (7.5) here it looks
Just sub in those
