Answer:
One Solution ; x=4.5
y=-1.5
Step-by-step explanation:
Line A: 2x+2y=8
÷<u>2</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>
x+y=4
Line B: x+y=3 -----> y=x-3
x+(x-3)=4
2x-3=4
2x=7
x=4.5
y=-1.5
B. 
Though ⅝ and 2.5 can be written in form of p/q where p is any real number and q ≠ 0.
But, in case of
, the decimal expansion of this number is non - terminating, non - repeating.
⇒ This is an irrational number.
Answer:
b. y -11 = 4/5(x -5)
Step-by-step explanation:
The slope of line passing through given points is: 2
Step-by-step explanation:
Let us define slope first
Slope is the steepness of a line
Slope is denoted by m
The formula for slope is:

Given points are:
(2,1) (-1,-5) and (3,3)
We will takes any two points to find the slope of the line passing through the points
So we take
(2,1) = (x1,y1)
(-1,-5) = (x2,y2)
Putting the values in the formula

The slope of line passing through given points is: 2
