When you graph a system of linear equations, why does the intersection of the two lines represent the solution of the system?

Every point on a line satisfies the related linear equation. A point that is on both lines (the intersection point) satisfies both equations.

Every point on a line does not satisfies the related linear equation

Every point on a line called slope of line.

Every point on a line called skew point.

I'll give brainliest if you answer right : )

Ineed to find the answer to number 2

Astudent is determining the influence of different types of food on the growth rate of spiders. she feeds one group of spiders two caterpillars twice a week. the other group received similarly-sized beetles twice a week. she records the amount of time required for individuals to reach sexual maturity. her hypothesis is that the spiders feeding on caterpillars will have a faster growth rate because caterpillars have a higher protein content compared to beetles. in this experiment, what is the dependent variable? spiders assigned to different feeding groups. time required to reach sexual maturity number of prey items fed twice a week. growth rates of each group.
