Hi all!

I'm Andrew, I'm 13, and I reaaaally have a hard time with math! Neway, the teacher said we'll be starting new lessons today. She gave us some hw,, but I wasnt able to get these last two.

1)If a line's slope is 2/3, and one endpt. is (-1,4), and the other endpt. is on the x axis,, what are the coordinates?

2)Show the graph of a line passng thru the midpoint of the line seg. whose endpts. are (3,5) and (-5,3), with slope= -1

Do you know how to write the equation of a line?

Are you familiar with the "standard form," the "slope-intercept form," and/or the "point-slope form" of a line equation?

I'm not sure how well you know about writing the equation of a line, which would determine how I would go about explaining how to do this problem.
