Answer:
(-10,-10)
Step-by-step explanation:
9x-9y=0
3x-4y=10
In elimination, we want both equations to have the same form and like terms to be lined up. We have that. We also need one of the columns with variables to contain opposites or same terms. Neither one of our columns with the variables contain this.
We can do a multiplication to the second equation so that the first terms of each are either opposites or sames. It doesn't matter which. I like opposites because you just add the equations together. So I'm going to multiply the second equation by -3.
I will rewrite the system with that manipulation:
9x-9y=0
-9x+12y=-30
----------------------Add them up!
0+3y=-30
3y=-30
y=-10
So now once you find a variable, plug into either equation to find the other one.
I'm going to use 9x-9y=0 where y=-10.
So we are going to solve for x now.
9x-9y=0 where y=-10.
9x-9(-10)=0 where I plugged in -10 for y.
9x+90=0 where I simplified -9(-10) as +90.
9x =-90 where I subtracted 90 on both sides.
x= -10 where I divided both sides by 9.
The solution is (x,y)=(-10,-10)

Answer:
B. (3,0)(0 ,-6)
Step-by-step explanation:
What is intercept.?
Intercept are those points where a given line cuts across a given axis.
So for the equation y = 2x - 6
To find the intercept we will bear in mind that we are looking for two points.
The point where the line cuts both the x axis and the y axis .
And to determine that, we will set both x and y to be equal to zero and then solve for both.
So let x = 0
Y = 2x -6
Y = 2(0) -6
Y = -6
One point = (0 ,-6)
Let y = 0
Y = 2x -6
0 = 2x -6
6 = 2x
X = 3
One point = (3,0)
The two points are
(3,0)(0 ,-6)
