Answer:
The lines are right on top of each other.
Step-by-step explanation:
Hi there!
The answer is -1.2857
Hope this helps!
You'd have to work out the gradient y=mx+c is the equation of a line, where m is the gradient, c is the y intercept (where the line cuts through the y axis) x is the x coordinate of the graph and y is the y coordinate on the graph
I can't see the complete picture, but I know the #2 is either C or D. You simply get one of the expressions and multiply it by 2 (because of its opposite side.)
And once you've done that for both expressions, add that together and you have your answer. Hope that helped.
