Answer:
Step-by-step explanation:
The slope is the difference in y-coordinates of the 2 points divided by the corresponding difference in x-coordinates.
For example:
Find the slope of the line joining the points (3, 5) and (-2, 1)
The slope = (5 - 1) / (3 - (-2))
= 4/(3+2)
= 4/5.
NOTE:
You would get the same result if you reversed the values
- that is (1 - 5)/(-2 - 3
= -4/-5
= 4/5.
The important thing to remember is to use <em>corresponding </em>values in the calculation.

Answer:
Value of the independent variable = 25
Step-by-step explanation:
y-intercept form of a straight line is represented by the equation,
y = mx + b
here y = dependent variable
m = slope
b = y intercept or vertical intercept
x = independent variable
In our question,
y-intercept 'b' = 150
slope of the line 'm' = 4
dependent variable y = 250
We will plug in these values in the equation of the line to get the value of the independent variable.
250 = 4x + 150
250 - 150 = 4x
x = 
x = 25
Therefore, value of the independent variable is 25.
