What is the y-intercept of the function f(x)= 4-5x?
–5
–4
4
5

Keywords:

equation, slope-intercept, slope, cut point

For this case, we have that by definition, the equation in slope-intercept form is given by: , where "m" is the slope and "b" is the cut point with the y axis. To find the slope, it is necessary to find two points through which the line passes and substitute in the following formula:

We have a function of the form , where . So:

that we can rewrite as:

Thus, we can identify that:

Thus, the cutoff point with the y axis is

Option C
