Question

Which procedure could be used to graph the line represented by the following equation?

y= 1/2x + 3

A) Plot the x-intercept (3, 0) and use the slope of 1/2 to find the second point.
B) Plot the y-intercept (0,3) and use the slope of 1/2 to find a second point.
C) Plot x-intercept (1/2, 0) and use the slope of 3 to find a second point.
D) Plot the y-intercept (0, 1/2) and use the slope of 3 to find the second point.

Answer 1

B, because the 3 represents the y- intercept, which is where the point hits the y-axis. So you start by plotting (0,3) and you go up one and over two.

Answer 2

y = mx + b......m is your slope and b is your y intercept.
so your y intercept is (0,3)..plot that and then use your slope (1/2 -- rise/run) to find your next point.
