Y=-1/2x+11 that passes through (4,-8)
kompoz [17]

A line in point-slope form has the equation


y = mx + b


where m=slope (increase in y for unit increase in x), and

b=y-intercept (value of y where line cuts y-axis)


The original line is

y=(-1/2)x + 11

so

slope = m = -1/2


Any line perpendicular to a line with slope m has a slope of m1=-1/m

So the slope m1 of the required line

m1 = -1 / (-1/2) = +2


and the required line therefore has an equation of

y=2x+b


Knowing that the line passes through P1=(x1, y1)=(4,-8), we can find b using the point slope form of a line with slope m : (y-y1) = m(x-x1)

where m=+2 as found above.


Substituting values, m=+2, x1=4, y1= -8

y-(-8) = +2(x--4)

simplify

y+8 = 2x-8

=>

y=2x-16 (in point slope form)

5. 18 m 11 m Not drawn to scale 29 m b. 445 m 7 m d. 203 m​
Luden [163]
Answer: D

Explanation: Apply the pythagorean theorem (a^2 + b^2 = c^2) to get 11^2 + b^2 = 18^2. From that you can solve for b and you get the square root of 203.

Hope this helped! :)
