Answer:

i believe the answer would be y= -x-4

Step-by-step explanation:

a line that is perpendicular, will have and opposite reciprocal slope, so:

the slope of the line y=x-4 is 1, and the reciprocal of 1 is also 1.

now take the opposite of it, which is -1.

so the perpendicular line equation would be y=-x-4

i hope this helps :D

$Answer: \\ {( {x}^{2} + 4) }^{2} + 32 = 12 {x}^{2} + 48 \\ \Leftrightarrow {a}^{2} + 32 = 12( {x}^{2} + 4) \\ \Leftrightarrow {a}^{2} + 32 = 12a \\ \Leftrightarrow {a}^{2} - 12a + 32 = 0 \\ \Rightarrow Coefficients:1, \: -12. \: Constant:a$

PLEASEE HELPP!!!!

y = - $\frac{1}{4}$ x + $\frac{15}{2}$

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

y = 4x + 5 is in this form with slope m - 4

Given the slope of a line m, then the slope ( $m_{2}$ ) of a line perpendicular to it is

$m_{2}$ = - (1 / m ) = - $\frac{1}{4}$

y = - $\frac{1}{4}$ x + c is the partial equation of the perpendicular line

to find c, substitute ( 2, 7 ) into the partial equation

7 = - $\frac{1}{2}$ + c ⇒ c = $\frac{15}{2}$

y = - $\frac{1}{4}$ x + $\frac{15}{2}$ ← equation of perp. line
