Question

MEDAL AND FAN pleas help me;^;

Which graph below shows a system of equations with no solution?

coordinate plane with two parallel lines
coordinate plane with two intersecting lines
coordinate plane with two coinciding lines
coordinate plane with two intersecting lines

Answer 1

Coordinate plan with two parallel lines has no intersection. Thus you could not solve a system with out expressing equality.

Answer 2

huh

Answer 3

the first one has no solution

Answer 4

witch means

Answer 5

Do you know what a system of equations is?

Answer 6

no ;-;

Answer 7

no worries,
a system of equation is when you have at least two equation and at least two unknowns like:
y = 2x + b
Y = 6x + 3b
Notice that you can not solve these equation individually, but you can solve the "system" as a whole.
i could say solve for one variable like x and then plug it into the other equation.

Answer 8
