Answer 1

Well do you know equation of a line? We can start with that then go into inequalities.

Answer 2

y=mx+b?

Answer 3

Yeah exactly, can you figure out the equation of the lines of the two given lines?

Answer 4

no not really

Answer 5

Ok no worries, so like the easiest way to find the equation of a line is, first knowing what all the variables mean, y=mx+b, m here is the slope, and b is the y - intercept (where the line crosses the y - axis).
The slope m can be found by using this equation \[m = \frac{ y_{2}-y _{1} }{ x _{2}-x _{1} } \] where (x1,y1), (x2,y2) are any two points on the same line.

Answer 6

I'm so confused so is it y3 and x-3?

Answer 7

sorry it's hard for me :/

Answer 8

lets first label the lines, 1 and 2, and now lets find the slope of the first line
