Hint: Use the number line to find the missing value.
-2=+6

Matt and brian were solving a system of equations. they both noticed that the two lines had the same slope. brian said that because each line in the system had the same slope, the two lines had to be parallel, which meant the solution to the system was "no solution" matt disagreed, and said they should also look at the y-intercepts before determining how many solutions there were. who is correct?

Which expression is equivalent to 2x^2+2x-4/2x^2-4x+2

What is the point-slope form of the equation for the line with a slope of -2 that passes through (1,4)?
