Write the equation of a line passing through (12,-1) with a slope of -4/5.

Hello!

So we want slope intercept form which is;

y=mx+b

Using your given values we can just plug into our equation and solve.

-1=(-4/5)(12)+b
b=-1+48/5
b=43/5 so now we have our last value which is the y-intercept

Now we get our final answer of;

y=(-4/5)x+43/5

Hope this helped you out some. Any questions please just ask. Thank you

Yes. there is a constant ratio of number of calories to gram of protein.12/3=24/4=32/8=44/11=4
