Example Question #54 : Calculus
What is the slope of the line:
Step 1: The current equation is in standard form, where x and y are both on one side of the equal sign..
Step 2: Change the equation to slope-intercept form.. Move the y to the other side
Step 3: Move the constant to the other side:
Step 4: Divide by the coefficient in front of :
Step 5: Split the left side into two fractions and simplify:
Step 6. Locate the slope. The slope is the coefficient of the x term.
The slope is , or
Example Question #31 : Coordinate Geometry
Find the y-intercept of the equation of a line:
Step 1: Subtract from both sides:
Step 2: Divide by the coefficient of the y term..In this case, divide by .
Simplify and separate fraction on right side:
Step 3: Locate the y-intercept (also known as b):
If we compare our equation to the general slope-intercept form: , we see that ..
