Standard Form & Point Slop Form & Parallel / Perpendicular

Front

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

Back

The point-slope form is given by the equation: y - y₁ = m(x - x₁), where (x₁, y₁) is a point on the line and m is the slope.

Front

Convert the point-slope form y - 5 = 2(x - 3) to slope-intercept form.

Back

y = 2x - 6 + 5, which simplifies to y = 2x - 1.

Front

Write the equation of a line in slope-intercept form that has a slope of 3 and passes through the point (1, 2).

Back

Using the point-slope form: y - 2 = 3(x - 1), which simplifies to y = 3x - 1.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Convert the equation y = -2x + 4 to standard form.

Back

The standard form is 2x + y = 4.

Front

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers.

Front

Write the equation of a line that is parallel to y = 5x + 2 and passes through the point (2, 3).

Back

The equation is y = 5x - 7.
