Subtracting 6 from both sides gives 2x = 8, then dividing by 2 yields x = 4.

Question 2

What is the slope of the line described by the equation y = 3x - 7?

Accepted Answer

3

Answer

In slope-intercept form y = mx + b, the coefficient m of x is the slope, which is 3.

Question 3

Which of the following represents a quadratic equation?

Accepted Answer

y = x² + 5x - 6

Answer

A quadratic equation has a degree of 2, meaning the highest power of the variable is 2, as in x².

Question 4
