REVIEW: Find the slope for the following situations. a. Given the equation y = 5x + 1 b. Given the equation 2x + y = 6 c. Given
the points: (2, 3) and (5, 9)
1 answer:
Answer:
Part 1) The slope is 
Part 2) The slope is 
Part 3) The slope is 
Step-by-step explanation:
Part 1) we know that
The equation of the line into slope intercept form is equal to

where
m is the slope
b is the y-coordinate of the y-intercept
In this problem we have

so
the slope is 
Part 2) we know that
The equation of the line in standard form is equal to

where
the slope is equal to 
in this problem we have

so

substitute


Part 3) we know that
The formula to calculate the slope between two points is equal to
we have
Substitute the values
