Answer:
A, B, & D
Step-by-step explanation:
<u>A: Linear functions are often written in point-slope form, y=mx+b.</u>
<u>B: The rate of change in linear functions is always a constant slope, the m value.</u>
C: The initial value of a linear function <em>could </em>be zero. It depends on the line.
<u>D: It makes sense that the graph of a linear function is a line.</u>
E: A vertical line <em>is not</em> a function. You can do the vertical line test: if a vertical line were to hit more than one point at a single x-value, the line is not a function.
