Question

What is the slope-intercept form equation of the line that passes through (3, 4) and (5, 16)?

y = 6x − 14
y = −6x + 14
y = −6x − 14
y = 6x + 14

Answer 1

The Answer is A. y = 6x − 14

Answer 2

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
