# Writing Equations in Slope-Intercept Form - Problem 1

If given the slope and the y-intercept, plug those values into the slope-intercept form of a line to find the equation. The value of the slope is substituted in form m and the value of the y-intercept is substituted in for y.

The slope intercept form of the equation of lines is one of my personal favorite because it’s pretty easy to work with. Remember a slope intercept form looks like this where m stands for your slope number and b is your y-intercept number. So this problem is going to take us 10 seconds or less.

Write the equation of the line in slope intercept form that y-intercept of (0,-3) and slope of 4. So here we are, we’re just going to plug in that y-intercept value, it’s going to go here for b and the slope number is going to go there for m.

My answer will look like y equals 4x take away 3. I only use the y value of the y-intercept, that’s it you guys. Slope intercept form can be really, really easy and not too bad especially if you’re given the slope and the y-intercept.
