Which is the equation of the given line in ponit-slope form?

A. y + 4 = 9/8(x + 1)

B. y + 1 = 8/9(x + 4)

C. y + 1 = 8/7(x + 4)

y - 1 = 8/9(x - 4)

(SAME IMAGE FOR QUESTION 2)

2.

Write the equation of the line in standard form.

A. -8x + 9y = 23

B. -8x + 9y = -23

C. -8x + 7y = 25

D. -9x + 8y = -23

Answer 1

Answer:

Answer:

1. B

2. A $(y+1)=(8)/(9) (x+4)\ny+1=(8)/(9) x+(8)/(9) *4\ny+1=(8)/(9) x+(32)/(9)\n9*(y+1=(8)/(9) x+(32)/(9))\n9y+9=8x+32\n-8x+9y=32-9\n-8x+9y=23$

Step-by-step explanation:

The point slope form of a line is $(y-y_1)=m(x-x_1)$ where $x_1=-4\ny_1=-1$ . We write

$(y--1)=m(x--4)\n(y+1)=m(x+4)$

To find m, count the slope from each marked point on the graph. Notice one is 1/2 so we will count by halves. The slope is 8/9

This means B is the point slope form. To convert to the standard form, it must be written as $ax^2+by^2=c$ . We convert using inverse operations.

Can you have 2 vertical asymptotes?

Answers

YES. you can have 2 vertical asymptotes.

So I'll set the denominator equal to zero and solve. Since I can't have a zero in the denominator, then I can't have x = –4 or x = 2 in the domain. This tells me that the vertical asymptotes (which tell me where the graph can not go) will be at the values x = –4 or x = 2. hope this helped.:)

A car salesperson earns a 18% commission on every car sold. The salesperson sells a car for $37,560. What is the commission?
