Algebra 1 Exam Review #1

Front

Back

The solution set is x > -11 and x < 3.

Front

How do you find the equation of a line given a point and a slope?

Back

Use the point-slope form: y - y1 = m(x - x1).

Front

What is the equation of a line that passes through the point (2, 3) with a slope of 4?

Back

y = 4x - 5.

Front

How do you determine the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

Find the equation of the line that passes through the points (1, 2) and (3, 6).

Back

y = 2x.

Front

What does it mean if an equation has no solution?

Back

It means there are no values of the variable that satisfy the equation.

Front

Back

The solution is b = 0.

Front

What does it mean if an equation has all real numbers as a solution?

Back

It means any value of the variable satisfies the equation.

Front

Back

The solution is all real numbers.

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.
