Question

Which linear function represents the line given by the point-slope equation y + 1 = –3(x – 5)?

f(x) = –3x – 6
f(x) = –3x – 4
f(x) = –3x + 16
f(x) = –3x + 14

Answer 1

first use distribution
\(-3(x-5)\\-3*x=-3x\\-3*-5=15\\y+1=-3x+15\)

Answer 2

what is 15 - 1 @jonestyrese15

Answer 3

i think the answer is d

Answer 4

you are correct ^_^

Answer 5

f(x)= -3x+14

Answer 6

@Imtiaz7 sort of late :P

Answer 7

can u help me with one more

Answer 8

sure

Answer 9

The equation of a linear function in point-slope form is y – y1 = m(x – x1). Harold correctly wrote the equation y = 3(x – 7) using a point and the slope. Which point did Harold use?

When Harold wrote his equation, the point he used was (7, 3).
When Harold wrote his equation, the point he used was (0, 7).
When Harold wrote his equation, the point he used was (7, 0).
When Harold wrote his equation, the point he used was (3, 7).

Answer 10

Yup :P@Mehek14

Answer 11

you have to find which point is on the line y = 3(x – 7)

Answer 12

which is (7,0)

Answer 13

so c

Answer 14

yes

Answer 15

Which equations and/or functions represent the graphed line? Check all that apply.

f(x) = 0.2x - 4
f(x) = 0.5x + 2
f(x) = x + 2
y – 3 = (x – 2)
y – 1 = 0.5(x + 2)

Answer 16

f(x) = 0.5x + 2

Answer 17

thts the only one

Answer 18

y – 1 = 0.5(x + 2)

Answer 19

those 2

Answer 20

ok

Answer 21

Which linear function represents the line given by the point-slope equation y + 1 = –3(x – 5)?

f(x) = –3x – 6
f(x) = –3x – 4
f(x) = –3x + 16
f(x) = –3x + 14
