m is 3/434
c is 5/454

Explanation:

All we have to do is separate this into two fraction using the rule to give us the linear equation for a line y=mx+cy=mx+c

(a+b)/c=a/c+b/ca+bc=ac+bc

f(x)=3/4x+5/4f(x)=34x+54

So 3/4 is mm or the slope

And 5/454 is c or the y intercept

The slope is 3/434 and the y-intercept is 5/454.

Explanation:

Given:

f(x)=(3x+5)/4=f(x)=3x+54=

f(x)=3/4x+5/4f(x)=34x+54

The slope-intercept form of a linear equation is:

y=mx+by=mx+b,

where:

mm is the slope and bb is the y-intercept.

Substitute yy for f(x)f(x).

y=3/4x+5/4y=34x+54

The slope is 3/434 and the y-intercept is 5/454.
