3x+2y=8
5x-2y=8
1) Cross out the 2ys and add the rest of the equations together.
2) 8x=16
3) 16/8=2 Therefore, x=2
4) Add 2 into one of the equations (either one)
5)3(2)+ 2y=8
6) 6+2y= 8
7) Subtractionnnnn 8-6=2
8) 2y=2
9) 2/2= 1
10) y=1 x=2 (2,1)
Answer:
-1
Step-by-step explanation:
Use rise over run, (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(9 - 4) / (1 - 6)
5 / -5
= -1
So, the slope is -1
Answer:
5a^2
Step-by-step explanation:
5ax5a=5a^2
Answer:
Option The graph will be a dashed line with a y-intercept of negative eight and a slope of three. The graph will be shaded above
the line
Step-by-step explanation:
we have

The solution of the inequality is the shaded area above the dashed line The equation of the dashed line is 
The slope of the dashed line is positive 
The y-intercept of the dashed line is -8
