(2,7)
(6,12)
(10,17)
Some moderator deleted my response for some reason. I did it mentally.. but I guess I'll show proof.
1) (2,7)
-4y = -5x - 18
-4(7) = -5(2) - 18
-28 = -10 -18
-28 = -28
2) (6,12)
<span>-4y=-5x-18
</span> -4(12) = -5(6) - 18
-48 = -30 - 18
-48 = -48
3) (10,17)
4y=-5x-18
-4(17) = -5(10) - 18
-68 = -50 - 18
-68 = -68
See the pattern? 2,6,10 and 7,12,17?

Formula to find the slope with two points: m=y2-y1/x2-x1, from the two points you were given (-2,-3) and (1,1). So m=1-(-3)/1-(-2)=4/3
Answer:
It's not correct
Because
Ratio is the comparison of two quantities having same units
So this ratio can't be taken
