So remember the transitive property here:
"If a = b and a = c, then b = c"
In this case, since y = -2x + 3 and y = -5x + 9, this means that -2x + 3 = -5x + 9. Substitute -5x + 9 into y of the first equation to solve for x:
Firstly, add 5x to both sides of the equation:
Next, subtract 3 on both sides:
Lastly, divide both sides by 3 and your first answer will be
Next, since we have the value of x, substitute it into either equation to solve for y as such:
<u>Putting it all together, your answer is (2,-1).</u>

How to solve 7-10: if a coordinate (x, y) is on the line, then f(x) = y.
7. Since x is 6, look at the graph, which shows that y (or f(x)) is 4. (look at picture)
8. Same thing as 7. you will see that f(x) is 15.
9. The other way around. since we know y = 2, looking at the graph shows us that x = 3.
10. Repeat process of 9. x = 10.
How to solve 11 + 12: slope formula (rise-over-run)
11. (14-4)/(12-6) = 10/6 = 5/3.
12. (16-14)/(18-12) = 2/6 = 1/3.
(If possible brainliest is appreciated :D)
