Answer:
y=6x-14
Step-by-step explanation:slope between (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
given
(3,4) and (5,16)
slope=(16-4)/(5-3)=12/2=6
y=6x+b
find b
sub a point
(3,4)
(x,y)
4=6(3)+b
4=18+b
minus 18
-14=b
y=6x-14
Answer:
y=6x-14
Step-by-step explanation:
to find the slope use the formula (Y2-Y1) over (X2-X1), or the y part of the second point minus the y part of the first point over the x part of the second point minus the x part of the first point:
16-4 12
-------- = -------
5-3 2
which simplifies to 6, 6/1, or -6/-1. once you have the slope, you can use it to find the y-intercept by simply counting units on a graph: in this case, 6 units up and one unit to the right or 6 units down and one unit to the left
