Question

Please help....
Identify the standard form of the equation of a line which has a slope of -1/2 and goes through (3,2)

a.)x+2y=7
b.)x-2y=7
c.)2x-y=7
d.)2x+y=4

Answer 1

y- b =m( x-a)

Answer 2

m is slope n line is passing through the point (a,b)

Answer 3

y-2= -1/2(x-3)

Answer 4

2y-4=-x+3
2y=-x+7

Answer 5

x+2y=7

Answer 6

y=-1/2x +C (constant) this means that it has slope of -1/2
to get the constant you only need to check what happens at x=3
at x=3 it is -1/2*3+C=2 so C is 7/2
multiplying with 2 give 2y=-x+7
So the answer is A.

Answer 7
