H=number of hours
m=total salary
m=15.50h+50
put 400 in for m
400=15.50h+50
now solve for h
400=15.50h+50
-50. -50
350=15.50h
Divide 350 by 15.50to get your final answer
you get a long decimal so I rounded it.
22.6 hours
<u>Answer:</u>
A line passes through the two given points (5,2), (5,-2). The line is vertical line
<u>Solution:</u>
Given, two points are (5, 2) and (5, -2)
We have to find that a line that passes through the given two points is vertical or horizontal or neither.
First let us find the slope of the line that passes through given two points.
So, slope of line m 
So slope of our line 
= undefined
Here slope of our line is undefined which means it is parallel to the y – axis.
Hence, line passing through given points is vertical line
Answer:
-9
Step-by-step explanation:
-9+6 can be rewritten to 6-9, which equals -3
Given data:
X Y
1 0
2 - 2
3 - 4
4 - 6
From the above table,
We have to see what sort of function is it showing.
Therefore,
Taking the first difference of the y-values.
We get,
-2 , -2 , -2
The first difference is constant for all the y-values, that is -2. Therefore it is a linear function,
So,
using the general form,
y = mx + b
where m represent the slope and b represents the y-intercept.
Now,
We will use two coordinate points to find out the slope,
Let them be: (1,0) and (2,-2)
So,
m = 2 / -1
m = -2
Now the y-intercept,
As we know that,
y = -2x + b
Take any point from the table, let it be (1,0)
substituting it into the equation, we get;
0 = -2(1) + b
b = 2
Hence our equation is:
y = - 2x + 2
