Which linear equation has a slope of 3 and a y-intercept of –2? y = 3x + 2 y = 3x – 2 y = –2x + 3 y = –2x – 3

The answer to this is y = 3x - 2. 

In the slope-intercept form y=mx+b, b is your y-intercept and in this problem, it will be -2. M is the slope which is 3. 

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

3cm and 6 and 9 cm that a possibility of that question
