Answer:
line l: x = -1
line m: x = 6
line n: y = 4
line p: y = -2
Step-by-step explanation:
All of these lines are parallel to either to y or x axis, so the slope is either zero or undefined. This means all you have to do is set x or y equal to the x intercept or y intercept. For lines that go vertically, they always have the same x coordinate and any y coordinate you put in will make a point that is on the line. The same thing with the horizontal lines, except they all have the same y coordinate and any x coordinate will make a point that is on that line.
All you have to do is set x or y, depending on which way the line is going, equal to the point is goes through on the axis it travels through, no need to worry about slope or y = mx + b.
Answer: C
Step-by-step explanation:
Assume x books are produced.
Then let 53808 + 12.5x = 17328 + 20.5x
Solve for x:
x = 4560

Step-by-step explanation:
Your first step is to solve for y on both equations.
You solve treat the inequality sign just like an equal sign and solve for it.
Graph your equations as if the inequality sign isn't there.
Use dotted lines for < and >
Use solid lines for ≤ and ≥
If it's less than, < or ≤, then shade underneath the line.
If it's greater than, > or ≥, then shade above the line.
