Question

How you you graph y = -2x + 1 ?

Answer 1

plug in x = 0 and evaluate to find y

what do you get?

Answer 2

y = -2x + 1

y = -2*0 + 1 ... plug in x = 0

y = ???

Answer 3

1

Answer 4

so you have one point (0, 1)

Answer 5

plug in x = 1

y = -2x + 1

y = -2*1 + 2

y = ???

Answer 6

ohhhhhhhhhhhh , I get the drift.

Answer 7

so what do you get for y ?

Answer 8

0 right ?

Answer 9

so you have the two points (0, 1) and (1, 0)

Answer 10

oh i made a typo, i just realized that...sry

Answer 11

plug in x = 1

y = -2x + 1

y = -2*1 + 1

y = -2+1

y = -1

So when x = 1, y is y = -1

Therefore, we have the point (1, -1)

Answer 12

so what you really have are these two points

(0,1) and (1, -1)

Plot them both. Then draw a straight line through them to graph y = -2x+1

Answer 13

what about y = -2/3 x + 1
