Write the standard form of the equation of the line through the given points. through: (-3,-1) and (5,-2)

You first have to find the slope using the slope formula.  That looks like this with our values:  .  So the slope is -1/8.  Use one of the points to first write the equation in y = mx + b form.  We have an x and a y to use from one of the points and we also have the slope we just found.  Filling in accordingly to solve for b gives us   and  .  Adding 5/8 to both sides and getting a common denominator gives us that  .  Writing our slope-intercept form we have .  Standard form for a line is Ax + By = C...no fractions allowed.  So let's get rid of that 8 by multiplying each term by 8 to get 8y = -x - 11.  Add x to both sides to get it into the correct form:  x + 8y = -11
