which equation represents the line that passes the point (1,5) and has a slope of negative 2?

Question

a) y=2x+7
b) y=-2+11
c) y=2x-9
d) y=2x+3

Answer 1

a) , c), and d) have a slope of 2
b) doesn't even have an x term

Now which equation does (1,5) fit into ???
put x = 1 into each right side of the equation and see if you get a y value of 5

Answer 2

a) was suppose to be -2x+7

so the answer would be a since it the answer is 5 right?
thanks so much :)

Answer 3

Ok, but what about d) ?????

y = 2x + 3
for (1,5)
5 = 2(1) + 3
5 = 2+3
5 = 5

your a)
y = -2x + 7
5 = -2(1) + 7
5 = -2+7
5 = 5
that works too,

so (1,5) lies on two different lines and (1.5) must be the intersection of
y = 2x+3 and y = -2x +7

Answer 4

wow that was a lot and that was funny

Answer 5

Which equation written in standard form has a graph that has a slope of negative2and 1 over 5 and passes through the point (negative10, 2)?
