Answer:
Step-by-step explanation:
We have been given an expression 
. We are supposed to combine like terms for our given expression.
We can see that 
are like terms as both of these terms have x variable.
Similarly, 
are like terms as both are constant.
Upon combining like terms, we will get:
Therefore, our required expression would be .
To plot a point on a graph, you need the x and y coordinates.
In this case, the x-coordinate is 2 and the y-coordinate is 2 thus you can plot
(2,2) on a graph.
To get the equation of a line, you need the slope m of the line, a point and another imaginary point (x,y). So in this question you still need the slope to find the equation.
The equation is : No
Answer
1. The point can be plotted on a graph
2. No, the equation can not be determined because the gradient is not known.
Answer:
Step-by-step explanation:
♨Rage♨
4. 6x + 5y = 4 a
6x-7y = -20 b
a-b
6x + 5y -6x+ 7y = 4+20
12y = 24
y = 2
Sub y in a
6x + 10 = 4
6x = 4-10
x = -6/6 = -1
5. 2x-3y=12 a
4x+ 3y = 24 b
b+a
4x+3y+2x-3y =36
6x=36
x=6
Sub x in a
12-3y = 12
-3y=12-12
y= 0/3 = 0
