High School Mathematics9.14 The Slope - Intercept Form of a Line

 A line with Y-intercept C and Slope m is y = mx+c. This form of a line is called the slope intercept form. Example: Find the equation of the line with slope 3 and y-intercept 2. Solution: Equation of line with a slope m and y-intercept c is y = mx + c. Given that, Slope = 3 and y-intercept = 2 Substituting in the above equation we get, y = 3x + 2 Which is the required equation. Directions: Find the equation of the line for the following questions. Also write at least 10 examples of your own.
 Q 1: Find the equation of the line with slope -3, y-intercept 5.y = 3x - 5y = 3x + 5None of thesey = -3x + 5 Q 2: Find the equation of the line with slope 2/3, y-intercept 7.y = (2/3)x - 7y = (2/3)x + 7y = (3/2)x + 7y = (3/2)x - 7 Q 3: Find the equation of the line with slope 3, y-intercept -8.y = 3x + 8y = -3x - 8y = -3x + 8y = 3x - 8 Q 4: Find the equation of the line with slope 2, y-intercept -15.y = 2x + 15y = 2x - 15y = -2x + 15y = 2x - 15 Q 5: Find the equation of the line with slope 4, y-intercept 18.y = -4x - 18y = 4x - 18y = 4x + 18y = -4x + 18 Q 6: Find the equation of the line with slope 8, y-intercept 17.y = 8x + 17y = 8x + 17y = -8x - 17y = -8x + 17 Question 7: This question is available to subscribers only!
