Question

Four students graphed one linear function each.

Rhett
On a coordinate plane, a line goes through points (negative 4, 0) and (0, 1).
Cameron
On a coordinate plane, a line goes through points (0, 4) and (1, 0).

Ellis
On a coordinate plane, a line goes through points (0, negative 4) and (2, 0).

Braden
On a coordinate plane, a line goes through points (0, 1) and (4, 0).


Which student graphed a linear function with a y-intercept at –4?

Answer 1

The x-intercept of a function is when the function crosses the x-axis, i.e. when y = 0.
The y-intercept of a function is when the function crosses the y-axis, i.e. when x = 0.

Now, which student graphed a line that has a y-intercept of -4?
Hint: the x-value should be 0 at the y-intercept of -4

Answer 2

For your question tiyon, which of the coordinates from the people listen has -4 as its y coordinate? for example (2, -4)
