Question

The graph of y = 1/2x + 3 is shown. Use it to solve the equation 1/2x + 3 = -1.
A) -8
B) -2
C) 2.5
D) 4

Answer 1

look at the graph what is the value of x when y = -1?

Answer 2

alternatively you could solve \[\frac{1}{2}x+3=-1\] in two steps

Answer 3

the value of x would be -1

Answer 4

subtract 3 from both sides
then multiply both sides by 2

Answer 5

and no, it would definitely not be -1

Answer 6

am i subtracting 3 from the one and 3 or from the 3 and 1/2
