Question 116022: What is the equation of a line that has a slope of 3/4 and a x-intercept of 0?
And how do you do it...more importantly.
a) what is domain?
b) how would you graph of a line with a slope of 1?
c) The line with equation y=10x-2 intersects the x-axis at the point (a, 0). What is the value of a?
Thanks.

Question 118868This question is from textbook McDougal Littell Algebra 1
: We are using McDougal Littrells Algebra 1 book for my math class. My teacher uses homework generated from a web site. I do not know the site so I'm having difficulty getting an explanation of it. Below are the instructions along with a few problems.
"Extra Practice 4.1
In 1-12, sketch the lines on the coordinate plane. Then find the point at which the lines intersect.
1.) x=3, y=2
2.) x=-2, y=4 "
I don't understand what I'm being asked to do; x and y in these problems are points on a graph rather than a line, and if they're treated as a slope and y intercept- it still only graphs a single line (which will intersect with nothing!) What am I missing here?This question is from textbook McDougal Littell Algebra 1
