No your friend I’d not correct although the slope is 4, the y-intercept is -3 because of the minus 3 in the equation.
The value that would make the ratios equal to 4 to 10... I believe it would be 2 to 5
to get the equation of any straight line, we simply need two points off of it, well, let's use the provided values hmmm
Louise’s answer is not correct. She is missing the term 30x3. When squaring a binomial, it is best to write the product of the binomial times itself. Then you can use the distributive property to multiply each term in the first binomial by each term in the second binomial. Louise also could have used the formula for a perfect square trinomial, which is found by squaring a binomial.
