Question

Complete the equation of the linear function.

y = __ x + __

A graph of a function. The function graph goes through point 0, 4 and point negative 1, 1.

Answer 1

the slope is .8. I don't know what that is in a fraction. the equation is y=.8x+4
0-4= -4
-5-0=-5 -4/-5= .8

y-4=.8(x-0)

y-4=.8x
+4 +4
y=.8x+4
Hope this helps...

Answer 2

is it 0.8 or just 8?

Answer 3

@TFIOS_GUS623 where does the graph touch the y axis?

Answer 4

at point 4

Answer 5

now let's find the slope do you know how to do this?

Answer 6

Not really... the formula confuses me, sorry.

Answer 7

let's go back first.

the equation of a line is

y = m(x)+b

where m = slope
b = y intercept

Answer 8

okay, so b=4 right?

Answer 9

yes :)

Answer 10

now let's find the slope we know that the graph goes through

(0,4)

(-2,-2)


\[\frac{ y_{2}-y_{1} }{ x_{2}-x_{1} } = m\]

Answer 11

okay so is it like, the y intercept for both and then the x intercept for both (or whatever you call them exactly)? i just get confused with the 2s and the 1s in it....

Answer 12

Pick your points and subtract in the direction i indicated. the slope just means the change in y over change in x.
