In each part that​ follows, you are given an equation of a line and a point. Find the equation of the line through the given poi
Semmy [17]

Answer:

a) y=-\frac{1}{9}x

b)y-2=-\frac{1}{3} (x-1)

Step-by-step explanation:

We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point given and a slope from the equation. We will chose point-slope since we have a point and can find the slope.

Point slope:y-y_1=m(x-x_1)

a) m\neq 9 in our new equation because it is perpendicular to it. This means we will need to change it into its negative reciprocal which is m=-\frac{1}{9}.

We will substitute m=-\frac{1}{9} and x_1=0\\y_1=0.

y-0=-\frac{1}{9} (x-0)

This simplifies to:

y=-\frac{1}{9}x

b) The equation y=3x+4 follows y=mx+b. For the perpendicular line, m\neq 3. We will need to change it into its negative reciprocal which is m=-\frac{1}{3}.

We will substitute m=-\frac{1}{3} and x_1=1\\y_1=2.

y-2=-\frac{1}{3} (x-1)

(2 12)-3 6)parethesis two plus twelve parethesis subtraction three plus six
ira [324]
You should use Order of Operations or PEDMAS for this (Parenthesis, Exponents, Division and Multiplication in the order they appear, Addition and Subtraction in the order they appear).  So we do the 2+12 because that is in parentheses first which gives 14-3+6.  Next we do 14-3 because there are no exponents and no division or multiplication, which gives 11+6.  This yields your answer, 17.
