A line has a slope of 1/4 and passes through point (0.4,-1/2). What is the value of the y-intercept?

AVprozaik [17]

Answer: The value of the y-intercept is $-\frac{3}{5}$

Step-by-step explanation:

The equation of the line in Slope-intercept form is:

$y=mx+b$

Where "m" is the slope and "b" is the y-intercept.

In this case we know that the line passes through point $(0.4,-\frac{1}{2})$ and has a slope of $\frac{1}{4}$ . Then we can substitute the following values into $y=mx+b$ :

$x=0.4\\\\y=-\frac{1}{2}\\\\m=\frac{1}{4}$

Then:

$-\frac{1}{2}=\frac{1}{4}(0.4)+b$

And finally, we must solve for "b":

$-\frac{1}{2}=\frac{1}{4}(0.4)+b\\\\-\frac{1}{2}-\frac{1}{10}=b\\\\b=-\frac{3}{5}$
