y=mx+b

anonymous · Answer

the slope would be 4/3 ...i just dont know how to find the y intercept from this

Still here? 
I'm glad you can find the slope, it's correct :)
Now you need to find the equation of the line, but that's easy.
When you have a slope $\color{green} m$  and a point $(\color{red} a \ , \ \color{blue}b)$

Then the equation of the line is given by...
$$\Large y = \color{green}m(x-\color{red}a)+ \color{blue} b$$

You actually have two points here, you may use any one of them for your point   $(\color{red} a \ , \ \color{blue}b)$

y=4/3(x+1)-3 
y=4/3x + 4/3-3
y=4/3x-5/3  is this correct?

terenzreignz · Answer

$$\Large y = \frac43x - \frac53$$

Yes, brilliant :)
Now to get the y-intercept, simply set x = 0 and solve for y.

Well done, there ;)

anonymous · Answer

y intercept = -5/3 and thanks !!(:
