What symbol is used to represent the concept of 'change in'?

• Delta (Δ)

• Alpha (α)

• Beta (β)

• Sigma (Σ)

What does a negative slope indicate about the direction of a line on a graph?

• It is horizontal.

• It is vertical.

• It falls from left to right.

• It rises from left to right.

What does a slope of zero indicate about a line on a graph?

• The line is horizontal.

• The line is falling from left to right.

• The line is vertical.

• The line is rising from left to right.

How is an undefined slope visually represented on a graph?

• With a vertical line

• With a diagonal line

• With a horizontal line

• With a curved line

When finding the slope from a graph, what does 'rise' refer to?

• The difference in y-values of two points

• The difference in x-values of two points

• The vertical distance between two points

• The horizontal distance between two points

• 7/4

• -4/7

• 4/7

What does it mean if the slope calculated between two points is 0?

• The line is vertical.

• The line is falling.

• The line is horizontal.

• The line is rising.

Given a slope of -2 and a point (-4, y), if the line also passes through (1,0), what is the value of y?
