1. Q2. points with equal y-coordinate are all in the same horizontal line: y = 1.3

Q3.
slope = -1/3, so it slopes down.
the other line has slope -1/2

So, is -1/3 greater or less than -1/2?

Q4.
y-intercept is at x=0
x-intercept is at y=0
check the points to see whether they fit the equation. If so, they are on the line.

standard form is Ax+By=C

3y-2x=7
3*4-2k = 7, so k=19/2
3(t-1)-2(t+1) = 7, so t=12

Q5. -5/-3
