Question

Which equation represents the line that passes through the point ( 4,3 ) -1/2

Answer 1

Answer:

y= -1/2x+5

Step-by-step explanation:

The formula you need to use is (y-y1)=m(x-x1)

x1=the x point provided

y1=the y point provided

m=the slope

Simply plug the numbers into the equation to start.

(y-3)= -1/2(x-4)    Now we need to distribute the slope to both terms inside the parenthesis.

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

-1/2(-4)= 2      Now you put them back into the equation.

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

At this point you can get rid to the parenthesis around y-3 because it is basically saying to take it times 1.

y-3= -1/2x+2    Finally to get y alone you would add 3 to both sides.

+3           +3

y= -1/2x+5
