2)(4x + 2). Indicate which student factored the trinomial completely and which student did not, and explain why.

What is the equation of a line perpendicular to y=-2/5X-1 that passes through (2,-8)
AysviL [449]

Answer:

y=\frac{5}{2}x-13

Step-by-step explanation:

Given the equation

y=-\frac{2}{5}x-1

comparing the equation with the slope-intercept formy=mx+b

Here,

  • m is the slope
  • b is the intercept

so the slope of the line is m = -2/5

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line,

so  the slope of the perpendicular line will be: 5/2

Therefore, the point-slope form of the equation of the perpendicular line that goes through (2,-8) is:

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

y-\left(-8\right)=\frac{5}{2}\left(x-2\right)

y+8=\frac{5}{2}\left(x-2\right)

subtract 8 from both sides

y+8-8=\frac{5}{2}\left(x-2\right)-8

y=\frac{5}{2}x-13

30.24

+16.26

-----------

46.50

It can't be the first two, and because .04+.06 are hundredths, it must be the third one.

He did not regroup hundredths when adding digits.
