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)

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. 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.
