Question

I have a question about slope intercept form. I have a slope of 1.5 and coordinates 0,0 and 1.9, 3
how do you put this in slope intercept form

Answer 1

slope intercept form of an equation is: \(y=mx+b\) , where m is the slope and b is the y-intercept
in your case, m=1.5 and you need to solve for b using the coordinates given (x,y)

Answer 2

and how do i solve the other part

Answer 3

using the coordinates given (either 0,0 or 1.9, 3), substitute a point in the slope-intercept equation that i just gave into (x, y) then solve for b algebraically

Answer 4

can u show me how

Answer 5

let's do the first step, substitute the slope first and tell me what you have

Answer 6

y=1.5x+b

Answer 7

right?

Answer 8

yes ^_^
then let's say we'll choose (1.9, 3)-->(x,y) ,
we substitute it in the formula that you have: \( 3=1.5(1.9)+ b\)
try to solve for b

Answer 9

wait, i just found something strange here,

if we will use the point (1.9,3), i got \(y=1.5x+0.15\)
but if we will choose the point (0,0) , i got \(y=1.5x\)

are the coordinates supposed to be on the same line or not necessary?

Answer 10

they are not on the same line but i figured out the equation so thank you for yoyur help!

Answer 11

no problem (^_^)
