In order to Sherman a line that is either parallel or perpendicular to another line, you first have to put the equation into slope intercept form. This means you have to solve for y.

3x+4y = 7
4y = -3x + 7
y = (-3/4)x + (7/4)
The slope of the line is -3/4. Online which is perpendicular would have a slope of 4/3, The negative reciprocal.

Now that you know the slope, you can write many different equations that would be perpendicular to the original.

y = (3/4)x + any y-intercept....Pick a number, any number... 7. ... y=(3/4)x+7
... -2 ...y = (3/4)x - 2. Literally you can pick any number.

The graph of y=x is shifted up 2 units and 3 units to the left. Which is the equation of the translated function?

krek1111 [17]

Check the picture below.

$y = x\implies y = \stackrel{A}{1}(\stackrel{B}{1}x+\stackrel{C}{0})+\stackrel{D}{0} \\\\\\ \begin{cases} \stackrel{\textit{2 units up}}{D=+2}\\\\ \stackrel{\textit{3 units left}}{C=+3}\\ B=1 \end{cases}\qquad \implies y = \stackrel{A}{1}(\stackrel{B}{1}x\stackrel{C}{+3})\stackrel{D}{+2}\qquad \implies y=(x+3)+2$

Reflect the point A(-2,1) over the line x = 1. What is the location of A'

Sonbull [250]

Answer: A(2,-1)

Step-by-step explanation:reflect means opposite sides so that means yu turn it around to make your new number !
