What is the awnser to the circled equations?

Step-by-step explanation:

We have to write an equation of a line which  passes through the given point (-9,2) and is perpendicular to the given straight line y = 3x - 12 ........... (1)

Now, equation (1) is in the slope-intercept form and the slope of the line is 3.

Let, m is the slope of the required line.

So, 3m = -1

{Since, the product of the slopes of two perpendicular straight lines is -1}

⇒

Therefore, the equation of the required line in slope intercept form is  

{Where c is a constant}

Now, this above equation passes through the point (-9,2) point.

So,

⇒ 2 = 3 + c

⇒ c = - 1  

Therefore, the equation of the required straight line is (Answer)

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
