Algebra Spiral Math

Algebra involves all of the following except:

• generalizations

• testing hypotheses

• calculating

• random guessing

Convert 4x + y = -12 into slope-intercept form. (don't use any spaces)

Solve the system of equations using algebra: y = 2x + 4 and y = x - 3

Give the answer as an ordered pair with parentheses and no spaces.

What is the value of y in the solution to this system of equations? 3x - 5y = 22 y = -5x + 32
