Question
Identify the equation in general form for the line with slope 3 and y-intercept –4
3x – y – 4 = 0
3x – y + 4 = 0
3x + y – 4 = 0
3x + y + 4 = 0
Hint:
Equation of a line, when its slope and intercept is given can be given as- y = mx + b, where m = slope and b = y-intercept.
The correct answer is: 3x – y – 4 = 0
GIVEN- Slope (m) = 3 y-intercept (b) = -4 TO FIND- Equation of the given line in general form SOLUTION- We know that equation of a line in slope intercept form is y = mx + b. Substituting values of m and b, we get- y = 3x + (-4) ∴ y = 3x - 4 ∴ 0 = 3x - y - 4 .......................... (Subtracting y from both sides) FINAL ANSWER- Option 'a' i.e. '3x – y – 4 = 0' is the correct answer to the given question.
