What is the equation of the line through the origin and (-8, -5)?

a.) y = 8/5x
b.) y = -8x
c.) y = -5x
d.) y = 5/8x

Solve 2x+y=3 x+y=5 in substitution method

Complete the solution of the equation. find the value of y when x equals to 6 4x+y=20

Aclassmate thinks that solving a system by graphing gives an exact answer when the lines appear to cross at a grid point, but only an approximate answer when they don't. explain why this isn't true.
