Equation perpendicular to y=-2x+5 and goes through point (-3,4)

Mathematics

Answer:

y = \frac{1}{2} x + \frac{11}{2}

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

y = - 2x + 5 ← is in slope- intercept form

with slope m = - 2

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{-2} = \frac{1}{2}, thus

y = \frac{1}{2} x + c ← is the partial equation

To find c substitute (- 3, 4) into the partial equation

4 = - \frac{3}{2} + c ⇒ c = 4 + \frac{3}{2} = \frac{11}{2}

y = \frac{1}{2} x + \frac{11}{2} ← equation of perpendicular line

How do I simplify this exponent problem???
Nikolay [14]

Hello from MrBillDoesMath!

Answer:

(3/4) a^(-5)b^(-3)c^2


Discussion:  

(18 a^-3b^2c^6)/ (24 a^2b^5c^4) =

(18/24) a^ (-3-2) b^(2-5) c^(6-4) =

                  as  a^-3/a^-2 = a ^ (-3-2) = a^(-5), for examples

(3/4) a^(-5)b^(-3)c^2


Thank you,

MrB
