Algebra 1- Semester 1 Review

Front

What is the equation of a line with a slope of -2/3 and a y-intercept of 5?

Back

y = -\frac{2}{3}x + 5

Front

Is (1, 2) a solution to the linear equation y = -\frac{2}{5}x + \frac{12}{5}?

Back

Yes

Front

What are perpendicular lines?

Back

Lines that have opposite reciprocal slopes.

Front

Solve for x: 8v - 4(v + 8) = 8

Back

x = 10

Front

Solve for x: -4(x - 5) + 5 = 45

Back

x = -5

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

What does it mean for two lines to be parallel?

Back

They have the same slope and will never intersect.

Front

What is the point-slope form of a linear equation?

Back

y - y_1 = m(x - x_1), where (x_1, y_1) is a point on the line.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

m = \frac{y_2 - y_1}{x_2 - x_1}.

Front

What is the definition of a linear equation?

Back

An equation that makes a straight line when graphed.
