7 + 2x = 15 What is the value of x?
- A (0,3)
- B (1,2)
- C (7,3)
- D (3,7)
That's Correct!
It's Wrong!
In the equation y = 7x + 3, to find where the line crosses the y-axis, you need to determine the y-coordinate when x is equal to 0. This is because the y-axis is where x = 0.
So, substitute x = 0 into the equation:
y = 7(0) + 3
y = 0 + 3
y = 3
The line crosses the y-axis at the point (0, 3).
