The slope-intercept form of an equation is y = mx + b. rewrite the equation in terms of the slope m

PSYCHO15rus [73]

Answer:

$m=\frac{y-b}{x}$

Step-by-step explanation:

So we have the equation:

$y=mx+b$

And we want to write it in terms of m.

So, let's subtract b from both sides:

$y-b=mx$

Now, let's divide both sides by x:

$m=\frac{y-b}{x}$

And we're done!

I’m assuming the numbers are 2/3 and 3/4 so find the common denominator. 2/3x4=8/12 and 3/4x3=9/12 so 8/12+9/12= 17/12 or 1 and 5/12
