# What is th equation for the line that has a slope of 5 and y-intercept of -3?

**y = 5x - 3**

### Find th slope if it exists of the line containing the pair of points -5-13 and -17-19?

First we note that the slope does exist between the two points because the two points do not have the same x co-ordinate. Next, we apply the slope formula. slope=(y2-y1)/(x2-x1) Note that it does not matter which point you call as 1 or 2, you will still get the same result. For this example we will call point (-5,-13) as point 1 and (-17,-19) as point 2. Therefore: slope=(-19-(-13)) / (-17-(-5)) = (-6) / (-12)…

### What you y equals mx plus b?

y=mx+b is a formula used in graphing linear equations. it is written in this form because of the importance of t edofferent variables. the m stands for the slope, or how much the line goes down or up when the x-value increases by one. The b is a little easier. The b stands for the y-intercept, or where on the y-axis does the line intercept with. To graph this, you would get the equation they…
