Answer:
-5
Step-by-step explanation:
There is different ways to solve methods of elimination but if you wanted to cancel y out you would multiply by the opposite sign....for example
7x + 5y = 19
-5 (2x + y = 19) ---> -10x -5y = 95
this would cancel out your y to solve for x so you can plug it back in and solve! hope this helps!!!
(7,5)(-4,-1)
slope = (-1-5) / (-4-7) = -6/-11 = 6/11
y - y1 = m(x - x1)
slope(m) = 6/11
(-4,-1)...x1 = -4 and y1 = -1
now we sub...pay close attention to ur signs
y - (-1) = 6/11(x - (-4) ...not done yet...
y + 1 = 6/11(x + 4) <===
The answer that I got was y=105
Hope this helps!
