Will give brainiest 1. 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

1. B

2. A

Step-by-step explanation:

The point slope form of a line is where . We write

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 . We convert using inverse operations.

900 degrees

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
