Help please! Identify an equation in point slope form for the line perpendicular to Y =-4x + 8 that passes through (-2, 7)

777dan777 [17]

Answer:

D. $y-7=\frac{1}{4}(x+2)$

Step-by-step explanation:

The point-slope form of a line is given by:

$y-y_1=m(x-x_1)$

The line given to us has equation; $y=-4x+8$ .

The slope of this line is -4. The of the line perpendicular to this line is the negative reciprocal of the slope of the given line.

Our slope of interest is therefore; $m=\frac{1}{4}$

Since the point goes through (-2,7), we have $x_1=-2,y_1=7$ .

We plug in the slope and the point into the point-slope formula to obain;

$y-7=\frac{1}{4}(x--2)$

The required equation is:

$y-7=\frac{1}{4}(x+2)$

5x + 7 - 2(-8x -1) = 7(x - 1)

love history [14]

Step-by-step explanation:

$5x + 7 - 2( - 8x - 1) = 7(x - 1) \\ 5x + 7 + 16x + 2 = 7x - 7 \\ collecting \: like \: \: terms \: \\ 5x + 16x - 7x = - 7 - 2 - 7 \\ 14x = - 16 \\ divide \: both \: side \: by \: 14 \\ \frac{14x}{14} = \frac{ - 16}{14} \\ x = - \frac{ 8}{7}$
