Algebra Basics

Question 1

Combining like terms

Answer 1

Freely combine addition and subtraction

Get rid of parentheses, multiplications and division signs / fractions first, then combine and simplify

Question 2

Point slope form

Answer 2

y - y1 = m(x - x1)

Where (x1 , y1) is what you have

Plug to get to slope intercept form and solve for other points

Question 3

slope intercept form

Answer 3

y = mx + b

Question 4

Graph linear inequalities

Answer 4

y < mx + b = all y points below line
(Dotted line)

y > mx + b = all y above line (dotted line)

y >= mx + b = all y above including line

y <= mx + b = all y below including line
