Slope intercept calculator is used to find the slope and intercept of a straight line. We can find the slope and y intercept of a straight line with the form of the equation y = mx + b. Here m is the slope of a line and b is the y intercept.

Example 1Find the slope and y intercept of the line 3x + 9y – 18 = 0.

Solution1:  Steps for finding slope and y intercept of the line are as follow

Step 1: The given equation of the line is

=>    3x + 9y – 18 = 0

Step 2: To find the slope and y intercept, we can write this equation into the form

=>    y = mx + b

Step 3: Shift the constant term and x term to the right of the equality

=> 9y = - 3x + 18

Step 4: Now divide the equation by 9 on both sides, then we get

=>  y = (-1) x + 2
3

From this we have slope = m = -1  and y – intercept = 2

Example 2: Find the slope and y intercept of the line 3x + 8y – 15 = 0.

Solution 2:  Steps for finding slope and y intercept of the line are as follow

Step 1: the given equation of the line is

=> 3x + 7y – 15 = 0

Step 2: To find the slope and y intercept, we can write this equation into the form

=>  y = mx + b

Step 3: shift the constant term and x term to the right of the equality

=> 7y = - 3x + 15

Step 4: Now divide the equation by 7 on both sides, then we get

-> Y= (-3) X   + 15
7             7

From this we have slope = m = -3  and  y-  intercept = 15
