What is an equation in slopeintercept form for the line that passes through the points (1, –3) and (3, 1)?
y = 3x + 1
y = x – 3
y = 2x + 5
y = 2x – 5

Best ResponseYou've already chosen the best response.0well then just plot one of your points and keep using your slope.. down two, right one, point. down two right one point. or vice versa up two, left one, point

Best ResponseYou've already chosen the best response.0then use slope int. form y=mx+b where m=slope and b=yint.

Best ResponseYou've already chosen the best response.1ok, so the slope intercept form of a line is \[y = mx + b\] and using your slope you have y = 2x + b so to find b pick a point (3, 1) and substitute x = 3 and y = 1 to find b. then you'll have the equation of the line.

Best ResponseYou've already chosen the best response.1but looking at your choices... your slope calculation is incorrect... (1  3)/(3  1)

Best ResponseYou've already chosen the best response.01 (3) = 4. 31= 2. so thats 4/2, simplified to 2/1= 2

Best ResponseYou've already chosen the best response.11  3 = 4 2 negatives make a positive so the slope is 4/2 or 2 so you have y = 2x + b substitute x = 3, y = 1 to find b and the equation of your line

Best ResponseYou've already chosen the best response.1thats it so your line is y = 2x  5
