5) x +
7) y + 7 = 6x
8) y – 3x = 12
9) 7 = 3y – 5x
10) 2x + 8 = 5y
For each of the functions given,
a) Graph each.
b) Any equations not solved for y should be changed immediately to y =.
c) On the tables provided,
i) Calculate the y value that goes with each of the x values.
ii) Plot the ordered pairs.
iii) Confirm the shape of the graph is what you said it was supposed to be (choices are
a line (linear), a V (absolute value), a U (parabola or quadratic)
