can some one help i have been working on this all day i will give you a medal A line has the given slope m and passes through the first point listed in the table . complete the table so that each point on the table lies on the line. M=2 X 0 1 2 3 Y 0

OpenStudy (mathstudent55):

A slope of 2, m = 2, is also a slope of 2/1. Slope is the difference in y divided by the difference in x. Slope is the ratio of the change in y to the change in x. Since the slope is 2/1, that means that for every change of 1 in x, y changes 2. You have point (0, 0) To get to point (1, ?), how much did x change?

this is new to me can you explain

OpenStudy (mathstudent55):

Look at this grid. Notice that the letter A is in the bottom left square. Now I tell you that the letter A can move only according to the following rule: A move is: go 1 square right and 2 squares up and stop there. Can you copy my drawing and show me where the A would end up after one single move? |dw:1378178713865:dw|

a would end up here did i do it right

OpenStudy (mathstudent55):

Good try, but you're a little off. Here. One single square to the right, followed by 2 squares up, ok? |dw:1378179318971:dw|

okay

OpenStudy (mathstudent55):

Great. Now I tell you to do one more move using the same rule. Where would A end up?

OpenStudy (mathstudent55):

Wow. You're walking too fast! Remember the rule is 1 square to the right followed by 2 squares up.
