Y=25x+100 get y intercept and slope or something like that

This form is y=mx+b
m is slope
b is y intercept
slope=25
y intercept =100

Y=mx+b // equation to determine the slope and y intercept.
m is equal to the slope you are looking for, therefore, 25 is your slope. And b is the y intercept which is 100. 

With algebraic expressions, you can’t add and subtract any terms like you can add and subtract numbers. Terms must be like terms in order to combine them. So, you can’t always simplify an algebraic expression by following the order of operations. You have to use the distributive property to rewrite the expression and then combine like terms to simplify. With numeric expressions, you can either simplify inside the parentheses first or use the distributive property first.
