[tex]m_1 = 6, m_2 = 5[/tex]In general, the functions are of the form
[tex]y = f(x) = mx +b[/tex]
The linear functions are
[tex]f(x) = 6x + 4\\f(x) = 5x -2[/tex]
Let [tex]m_1 = 6, m_2 = 5[/tex].
A. False: the lines are parallel if [tex]m_1 = m_2[/tex] but this does not happen.
B. False. The lines are perpendicular if [tex]m_1m_2 = -1[/tex] and clearly this does not happen.
C. [tex]6x + 4 = 5x - 2\\x = -6\\6(-6) + 4 = -32 = 5(-6) -2[/tex]
Then C is true.
D. False. The lines are not the same.
A.
[tex]y - 5 = -2(x-6)[/tex]
Negative reciprocal gives you the perpendicular slope so negative reciprocal of 1/2 is -2.
Then apply point-slope form.
B. The answer is x = 6.
The midpoint of JK is
[tex]\left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right) = \left( \frac{8+ 4}{2}, \frac{4 + 4}{2} \right) = \left(6,4\right)[/tex]
The line that goes through JK is just a horizontal line [tex]y = 4[/tex] because the y-coordinate does not change. So its perpendicular bisector is the vertical line that goes through the x-coordinate of the midpoint, that is, [tex]x = 6[/tex].
Q1 5:3
Step-by-step explanation:
500 / 100 = 5
300 / 100 = 3
500:300 simplified to 5:3
y = 1/4x + 17/4
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Perpendicular lines have the negative reciprocal slope.
m = 1/4
y = 1/4x + b
4 = 1/4(-1) + b
4 = -1/4 + b
17/4 = b
y = 1/4x + 17/4
You do not have any points to right the point slope form.

Point slope form is [tex]y-y1=m(x-x1)[/tex]
Since we have to write the equation of a perpendicular line we will have to use the slope that is opposite and reciprocal.
[tex]y - (-1) = - \frac{1}{5} (x - (-2))[/tex]
[tex]y + 1 = - \frac{1}{5} (x + 2)[/tex]
Hope this helps :)
y-9 = -1/12(x-8)
Step-by-step explanation:
To write an equation of a line perpendicular to the graph of y = 12x-3 and passing through the point, we will follow the following steps.
The standard form of point-slope form of the equation of a line is given as
y − y1 = m(x − x1),
m is the slope of the unknown line
(x1, y1) is a point on the line.
Step 1: We need to calculate the slope of the known line first,
Given y = 12x-3
from the equation, m = 12 on comparison.
Step 2: get the slope of the unknown line. since the line given is perpendicular to the line y = 12x - 3, the product of their slope will be -1 i.e Mm = -1
M = -1/m
M is the slope of the unknown line
M = -1/12
Step 3: We will substitute M = -1/12 and the point (8, 9) into the point-slope form of the equation of a line i.e y − y1 = M(x − x1),
M = -1/12, x1 = 8 and y1 = 9
y-9 = -1/12(x-8)
The answer would be c
answer: it's d
