If given the slope and the yintercept, plug those values into the slopeintercept form of a line to find the equation. The value of the slope is substituted in form m and the value of the yintercept 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 yintercept number. So this problem is going to take us 10 seconds or less.
Write the equation of the line in slope intercept form that yintercept of (0,3) and slope of 4. So here we are, we’re just going to plug in that yintercept 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 yintercept, 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 yintercept.
