Consider the line containing the points c(2,9) and d(−1,4).

a: what is the slope of the line?
b: what is the equation of the line in point-slope form?

select one answer choice for question a, and select all correct answer choices for question b.

a: −35
b: y+4=35(x−1)
b: y+9=−35(x+2)
a: −53
b: y−9=35(x−2)
b: y−9=−53(x−2)
a: 53
b: y−9=53(x+2)
b: y−4=35(x+1)
b: y−9=53(x−2)
b: y−4=53(x+1)
a: 35

5/3 and y -9 = 5/3(x - 2)

5/3 and y - 4 = 5/3(x + 1)

Step-by-step explanation:

To write the equation of a line, calculate the slope between points (2,9) and (-1,4). After, substitute the slope and a point into the point slope form.

Substitute m = 5/3 and the point (2,9) into the point slope form.

You could choose to use the other point (-1,4). Repeat the same process substituting m = 5/3 and the point (-1,4).

Step-by-step explanation:

The point-slope form of an equation of a line:

m - slope

The formula of a slope:

We have the points C(2, 9) and D(-1, 4). Substitute:

For the point C(2, 9):

For the point D(-1, 4):
