What is the y-intercept of the line described by the equation below?y = 7x + 4A.(0, -7)B.(0, -4)C.(0, 4)D.(0, 7)
Question
What is the y-intercept of the line described by the equation below?y = 7x + 4A.(0, -7)B.(0, -4)C.(0, 4)D.(0, 7)
Solution
The y-intercept of a line is the point where the line crosses the y-axis. This is when x = 0.
The equation of the line is y = 7x + 4.
To find the y-intercept, we substitute x = 0 into the equation:
y = 7(0) + 4 y = 0 + 4 y = 4
So, the y-intercept of the line is (0, 4).
Therefore, the correct answer is C.(0, 4).
