Answer:
I prefer to express solutions to inequalities using interval notation. Both formats are are important but I think interval notation is easier to understand and represents better the solutions.
For example, if you have the following inequation:
x-2> 1
x>3
Therefore, the solution could be written either x>3 OR (3, +inf). But what happens if the solution to the system of equation is x>3 or x<-3? The solution can be easily written as: (-inf, -3) U (3, inf) instead of 'x>3 or x<-3' which can be confusing.
A+B+C = 180
62+95+Z = 180
157 + Z = 180
Z = 23
Answer:
The arrangement of the given equation in the slope - intercept form are
1.
Step-by-step explanation:
Given:
Let A ≡ ( x1 , y1 ) ≡ (-12 , 70)
B ≡ ( x2 , y2 ) ≡ (-4 , 78)
Slope - intercept form :
Where,
m is the slope of the line.
c is the y-intercept.
When two points are given say ( x1 , y1 ) and ( x2 , y2) we can remove slope by
Slope,
∴ 
Now equation of a line for a point ( x1 , y1 ) and having slope m is given as,

Which is in the required form
y = 1x + 82
Intercepts: Where the line cut X axis called X- intercept and where cut Y axis is called Y- intercept.
