Functions Quiz Paper Portion question 1
y= 4x-1

Answer:
See attached
Step-by-step explanation:
[] Using this equation and the y-intercept (when x = 0) we can solve for the table, and then plot the points on the graph.
[] We know that when x is 0 y will be -1 because of the intercept.
-> Then we can plug the rest of the points in.
y = 4(-1) - 1
y = -4 - 1 = -5
-
y = 4(1) - 1
y = 4 - 1 = 3
-
y = 4(2) - 1
y = 8 - 1 = 7
[] Last, we can graph the points we just found.
