Writing equations review

Front

True or false: The x-intercept of a function ALWAYS occurs where y is equal to zero.

Back

True

Front

Write the equation in point-slope form of the line that passes through the given point and has the given slope: (4, -7); m = -1/4

Back

y + 7 = -1/4(x - 4)

Front

True or false: The y-intercept of a function ALWAYS occurs where y is equal to zero.

Back

False

Front

Which equation is parallel to: y = 5/7x + 2?

Back

y = 5/7x + 5

Front

If m=3 and b=6, what is the correct slope intercept equation?

Back

y = 3x + 6

Front

What is the definition of the slope of a line?

Back

The slope of a line is the ratio of the rise (change in y) to the run (change in x) between two points on the line.

Front

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

Back

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

Front

How do you find the x-intercept of a linear equation?

Back

Set y = 0 in the equation and solve for x.

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.

Front

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

Back

y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.
