Step-by-step explanation:
multiplying the 2nd eqn by 9 we get,
9x+9y=81
then,subtracting 1st and 2nd eqn
9x+5y=41
9x+9y=81
- - -
__________
0. -4y=-40
we get y = 10
then we get x=9-y
x=9-10
x= -1
so x is -1 and y is 10
No..... (I'm just adding so brailny accepts it)
The lenght of each diagonals is 1.
Yes it is right (-10, 34) is a solution of y = 3x-4
A slope of 3/2 passing through (-3,0) gives us slope intercept form of
y - 0 = (3/2) (x - -3)
y = (3/2) x + 9/2
That's a y intercect of 9/2
Choice D
