Question

1. What is the y-intercept in the following equation? Explain. y = 1/2x

Answer 1

The slope-intercept form of the equation of a line is

y = mx + b

where m = slope, and b = y-intercept.

Now compare the form above with what you are given.

y = mx + b
y = 1/2x

You can write your equation as y = 1/2x + 0.

That shows that the slope, m, is 1/2 and the y-intercept, b, is 0.
