Y=7x-7

The slope intercept form would be y=Mx+b

The m in the equation is the slope
The b in the equation is the y-intercept

You can substitute these values in the intercept form.

y=Mx+b
y=(7)x+(-7)
y=7x-7

Anita took 1/6 of a cake and Barry took 60% of what remained. What fraction of original cake is left. Explain full method.

Sedaia [141]

The cake = 1
1-1/6=5/6
60% as a fraction =3/5
5/6-3/5
25/30-18/30
7/30
There are 7/30 of the original cake left.

Hope this helps :)
