Question

which equation represents the line that passes through the point (1,5) and has a slope of -2 ?
A. y=-2x+7
B. y=-2x+11
C. y=2x-9
D. y=2x+3

Answer 1

First of all, that means that y = -2x

Answer 2

First pick out the ones that have slope -2. Which ones are they?

Answer 3

Then you draw the line

Answer 4

I guess we are all more interested in the question than the asker who has disappeared.

Answer 5

a simple way is to understand the slope intercept form of a line

y = mx + b

m = slope and b = y intercept

so you know m= -2

so the line is

y = -2x + b

to find b, substitute x = 1 and y = 5 to find b

then you'll havee your line

Answer 6

x = 1 and y = 5 come from the point you are given (1, 5)

hope it makes sense
