Fist find the slope. The equation is m=y2-y1/x2-x1. Then use slope point form and select a point. Then use the equation y-y1=m(x-x1). Simplify and isolate y.

In the following exercises, multiply the binomials. Use any method.<br> 241. (x + 8)(x + 3)

Lelu [443]

Answer:

Hence the expression $(x+8)(x+3)=x^{2}+11 x+24$ .

Step-by-step explanation:

- The given expression is (x+8)(x+3).

- We have to multiply the given expression.

- Multiply the (x+8) by 3 , multiply the (x+8) by x then add like terms.

$\begin{array}{r}x+8 \\\underline {\times \quad x+3} \\3 x+24 \\\underline {x^{2}+8 x+24} \\x^{2}+11 x+24\end{array}$

Find the slope between the points. (4,-2) and (8,5)

aksik [14]

Slope = m

Equation to find slope is:

m = (y2 - y1) / (x2 - x1)

2 points:
(4,-2) 4 = x1 and -2 = y1
(8,5) 8 = x2 and 5 = y2

So...

m = (y2 - y1) / (x2 - x1)

m = (5 - (-2)) / (8 - 4)

m = 7 / 4 or 1.75

Therefore, the slope of the line is 7/4 OR 1.75.
