Question

Joan wrote a linear function.

Tell whether each statement about a linear function is true or false.

Answer 1

True, True, False, True, True

Explanation:

Question A: A linear function needs to be represented with a linear equation. For an equation to be linear it needs to be in the form y=mx+b or y=mx.

Question B: Rate of change is another word for slope. The slope needs to be constant or it won´ be linear.

Question C: It doesn't matter what the initial value is because it doesn't affect the slope. It could be 74 or it could be 0.

Question D: It needs to be a line because that´s literally half of the name and if it was not a line it wouldn't be a constant slope.

Question E: Yeah it could be a vertical line. It still has a slope, but it is just 0.
