Front

What is the slope in the equation y=2x + 3?

Back

2

Front

Find the slope of the line that passes through (-9, -6) and (-9, -10)

Back

Undefined

Front

What is the equation of this line? (Graph shows a line with a negative slope passing through (0, 2))

Back

y = -x + 2

Front

Which of these represents slope-intercept form? (Options: y - y1 = m(x-x1), Ax + By = C, y = mx + b)

Back

y = mx + b

Front

What type of slope does the graph have? (Graph is horizontal)

Back

Zero

Front

What does 'slope' represent in a graph?

Back

The steepness or incline of a line, calculated as rise over run.

Front

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

Back

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

Front

What is the y-intercept in the equation y = mx + b?

Back

The value of y when x = 0, represented by b.

Front

What does a positive slope indicate about a line?

Back

The line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

The line falls from left to right.
