Question

3. What is the graph that represents y = x-3

Answer 1

Option C

Explanation:

By looking at the equation y = x - 3 we can see that the slope is positive (so the line will have an upward trend) and that the y intercept is - 3 (which mean the line will go through the y axis in that point. So now we have two following statement....

• line has an upward trend
• line has the y intercept of (0,-3)

The only line following this statements is line C.

Answer 2

Option C

Explanation:

-3 is the y intercept so the graph should intersect at -3 on the y axis.

x is positive so the graph should point up.
