Question 230071: find an equation of the line containing the given pair of points. express your answer in the y=mx + b
(-6,-6) and (9,9) What is an equation of the line? y= ?

First you need to find the slope using the formula m=(y2-y1)/(x2-x1). I will leave you to do the arithmetic but you should find that the slope is 1.
So now we plug into the equation y=mx+b and we solve for b. Again I will leave you to plug in the points and solve but weither you plug in (9,9) or (-6,-6) you will find that b = 0.
So now we know that the equation of the line is y = mx+b and we know m and b so plugging in we get y = 1(x)+0 or y = x.
