Find the equation of the line with slope m=-3 passing through (-2,0)

Tell me how you got the it use the figures to answer questions 1and 2. in each diagram, line k is parallel to line l, and line t intersects lines. 1. based on the diagrams, what is the value of x? 2. how would you verify your answer for x?

Xto the second power plus 14x plus 48. what are the factors? we are doing factoring trinomials with a=1

Ineed in figuring out this problem.
