how to find y intercept of line y= 4x+12
For any equation in x and y,
to find the x-intercept, let y = 0 in the equation
to find the y-intercept , let x = 0 in your equation
of course you should be familiar with the form y = mx + b
where b is the y-intercept
For yours it would be 12
y = mx+b
is called the slope-intercept form for a reason ...
To find the y-intercept of a line, you need to identify the value of y when x is equal to zero.
In your equation, y = 4x + 12, you can substitute x with 0:
y = 4(0) + 12
When you simplify the equation, you find:
y = 0 + 12
Therefore, the y-intercept of the given line is 12.
