What is an equation in slope-intercept form for the line that passes through the points (1, -3) and (3,1) y= 3x + 1
y=x-3
y=2x+5
y= 2x – 5

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

answer: the common difference is -0.10
