A meteorologist used the expression below to describe how the temperature changed. –5 + (–4) Which statement could describe how the temperature changed?

you can't solve x because it is 2 linear equation and you only have one equation

step-by-step explanation: s

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
