1. Given the following table: (Topics: Use the definition of linear, use a table of data to find a linear equation, show work in organized manner) (a) Show evidence and write a justification of why this data is linear. (Note: a graph is not a sufficient justification) (b) Find the equation of the line that fits the data. X y (a) 3 -8 x-x 7 -10 2. Find the x- and y-intercepts of: 3x+2xy-4y=48. (Topics: Find x-intercept from equation, find y-intercept from equation, solving linear and quadratic equation, show work in organized manner 10 -11.5 3. Simplify each of the following expressions: (Topics: Convert radicals and fractional exponents, properties of exponents, distributive property, combining fractions, factoring) (b) (x/3-x-1/3) 1.
