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 1: Find 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

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

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