What is an equation in slope-intercept 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

well 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

then use slope int. form y=mx+b where m=slope and b=y-int.

  • campbell_st
ok, 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.

so b=7?
campbell_st
  • campbell_st
but looking at your choices... your slope calculation is incorrect... (1 - -3)/(3 - 1)

ohh...

  • campbell_st
lets get the slope right 1st
anonymous
  • anonymous
I still got -2..
anonymous
  • anonymous
1- (-3) = -4. 3-1= 2. so thats -4/2, simplified to -2/1= -2
campbell_st
  • campbell_st
1 - -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
anonymous
  • anonymous
so b= -5?
campbell_st
  • campbell_st
thats it so your line is y = 2x - 5
