Answer:
yes, it is
Step-by-step explanation:
plug in the point (1, -1) (x,y) into the equation y = 9x - 10
-1 = 9(1)-10
-1 = 9-10
-1=-1
Answer:
Factoring
Step-by-step explanation:




and 
From what I got there is one real solution :)
Rearrange the second equation to give y=2-2x, substitute into the first equation to give you a value for x and then using that you can work out y for the exact coordinates of intersection :)
Also they are both straight line graphs so they will either have one or no solutions
Hope this helped :)
Answer:
Exact form : x=6/5
Decimal form : x=1.2
Mixed Number form : x=1 1/5
Step-by-step explanation: Solve for x by simplifying both sides of he equation, then isolating the variable.
Hope this helps you out! ☺
