EOC Algebra 1 Full Linear Unit Milestone Review

Front

What is the explicit formula for the sequence 2, 8, 14, ...?

Back

a_n = 6n - 4

Front

How do you find the equation of a line given two points?

Back

Use the slope formula m = (y2 - y1) / (x2 - x1) and point-slope form y - y1 = m(x - x1).

Front

What is the solution to the system of equations y = 2x + 1 and y = -x + 4?

Back

(1, 3)

Front

How do you graph the equation y = 2/3x - 3?

Back

Plot the y-intercept (0, -3) and use the slope (rise/run) to find another point.

Front

What is the recursive formula for the sequence 4, 8, 12...?

Back

a_n = a_{n-1} + 4

Front

What is the definition of a linear equation?

Back

An equation that makes a straight line when graphed, typically in the form y = mx + b.

Front

What does the slope of a line represent?

Back

The rate of change of y with respect to x, indicating how steep the line is.

Front

How do you convert a recursive formula to an explicit formula?

Back

Identify the pattern in the sequence and express it in terms of n.

Front

What is the y-intercept of the line y = -2x + 4?

Back

The y-intercept is 4.

Front

What is the significance of the point (1, 3) in a system of equations?

Back

It is the point where the two lines intersect, representing the solution to the system.
