Best way to solve would be using Elimination Method. Here's how to solve.
9x + 8y = 15
9x + 8y = 30
To cancel out a variable multiply one equation with -1.
9x + 8y = 15
-1(9x + 8y = 30)
Distribute.
9x + 8y = 15
-9x - 8y = -30
Add both equations together.
0 = -15
So no solution would be your answer. I hope this helps love! :)
Answer:
70
Step-by-step explanation:
The slope is down 1 over 1.5, so that means Start with the slope formula
m=
(y2 - y1)
(x2 - x1)
Substitute point values in the formula
m=
(140 - 280)
(2 - 4)
Simplify each side of the equation
m=
(140 - 280)
(2 - 4)
=
-140
-2
Solve for slope (m)
m= 70
Booommmm, Im proud of this lol, hope it helps <3
