Question

The graph passes through (2,4) and (3, 9)

Answer 1

what u have to find?
is it a straight line?

Answer 2

The linear functions

Answer 3

Sorry

Answer 4

do u want the equation?

Answer 5

I think so

Answer 6

the direction just say find the linear function satifyuing the given conditions

Answer 7

\[ y = 5 x-6\]

Answer 8

how did you come up with that if I might ask

Answer 9

Sure.
it says to find that function,
(2,4) and (3, 9)
first of all find it's slope.

m = (9-4)/(3-2)
m = 5

then y intercept =
y = 5x +b
4 = 5(2) + b
b = -6

finally,

y = mx + b
y = 4x -6

Answer 10

ok what is the formula for the y intercept or is there one?

Answer 11

No, there is no formula for it.

to find the y-intercept, you have to insert the value of slope and any one cordinate.
finally, solve for "b: to get the answer.

Answer 12

ok that makes sence
