Find the yintercept of the two coordinates ( 2, 5) and ( 6, 3). Please help me with this question and please explain to me and show me how to find Each step to solving the y intercept. Thank you 😄

bobpursley,
y intercept is when x is zero.
y=mx+b
point 1 5=2m+b
ponit 2 3=6m+b
subtract second equation from first
8=4m
m=2, putting that in the first equation
5=4+b or b=1
y=2x1
so for y intercept, x is zero, or y=1

Lucy,
Thanks but my teacher said that the answer is y= 2x  9

Reiny,
slope = (3+5)/(62) = 8/4 = 2
so the equation is y = 2x + b
plug in one of the points: (6,3)
3 = 2(6) + b
9 = b
so y = 2x  9
Since this is in the yintercept, slope form , and b is the yintercept
there it is!!
