Hello there!

To find the slope of a line, we need to know at least two points contained in the graph of the line.

The slope $m$ of a line passing through the points $(x_0,~y_0)$ and $(x_1,~y_1)$ is given by the formula: $m=\dfrac{y_1-y_0}{x_1-x_0}$ .

As we can see on the graph, two points contained on the line are $(-2,~0)$ and $(3,~4)$ .

Using the formula above, we get that:

$m=\dfrac{4-0}{3-(-2)}$

Subtract the values on both numerator and denominator of the fraction

$m=\dfrac{4}{5}~~\checkmark$

This is the slope of this line we were looking for.

Factor completely 3X^2 -25

In order to factor a polynomial, you have to find its roots

$x_1,\ x_2,\ldots,x_n$

So that you can factor it as

$p(x)=(x-x_1)(x-x_2)\cdots(x-x_n)$

So, in this case, we're looking for the solutions of

$3x^2-25=0 \iff 3x^2=25 \iff x^2 = \dfrac{25}{3} \iff x=\pm\sqrt{\dfrac{25}{3}}=\pm\dfrac{5}{\sqrt{3}}$

So, the polynomial can be written as

$3x^2-25 = \left(x-\dfrac{5}{\sqrt{3}}\right)\left(x+\dfrac{5}{\sqrt{3}}\right)$

3.5 times as much flour as chocolate chips....
f = 3.5c
f = 1 3/4 (or 1.75)

1.75 = 3.5c
1.75 / 3.5 = c
0.5 = c......chocolate chips needed would be 1/2 a cup
