Write an equation in point-slope form of the line that passes through the two given points. Use the first point to write the equ

LekaFEV [45]

Answer:

The equation in point-slope form of the line is:

$y-\left(-5\right)=\frac{7}{4}\left(x-\left(-1\right)\right)$

Step-by-step explanation:

Given the points

(-1, -5)

(3, 2)

$\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(-1,\:-5\right),\:\left(x_2,\:y_2\right)=\left(3,\:2\right)$

$m=\frac{2-\left(-5\right)}{3-\left(-1\right)}$

$m=\frac{7}{4}$

As the point-slope form is defined as

$y-y_1=m\left(x-x_1\right)$

where m is the slope.

substituting the values m=7/4 and the first point (-1, -5)

$y-\left(-5\right)=\frac{7}{4}\left(x-\left(-1\right)\right)$

Therefore, the equation in point-slope form of the line is:

$y-\left(-5\right)=\frac{7}{4}\left(x-\left(-1\right)\right)$

stealth61 [152]

Answer:

The product is the difference of squares is $\left(5-3x\right)\left(5+3x\right)=25-9{{x}^2}$

Step-by-step explanation:

Explanation

The given expression is (5-3 x)(5+3x).

We have to multiply the given expression.

Square the first term 5. Square the last term 3x.

$\begin{aligned}&(5-3 x)(5+3 x)=(5)^{2}-(3 x)^{2} \\&(5-3 x)(5+3 x)=25-9 x^{2}\end{aligned}$
