Question

You are given an equation of a line and a point. use substitution to determine whether the point is on the line.

y=3x+7; A(2,13

Answer 1

(1,10) That is the slope, if there is another line then the answer will be different!

Explanation:

This is the slope-intercept formula, (y=mx+b)

Start by finding the y-intercept which is Positive 7 or plus 7 you should find it on the y-axis on the positive side.

Then you will need to identify the slope, the slope, in this case is 3, which needs to be in rise over run formula so 3 over 1.

To find a slope you must start at the y-intercept in your case is 7, then you must go up 3 and right 1.

Then identify the x and y axis.

If this is not the answer please provide this equation and another one to get them intersecting to get one point.
