Question

Is the point (1,4) on the line y=2x+3?

Answer 1

No, it’s not. By the way, there’s this website you can use to put in a function and see it on the graph. Just search up “Desmos graphing calculator” it’s so helpful!

Answer 2

No

Explanation:

The line y=2x+3 has a slope of 2 and a y intercept of (0,3). Plugging in x=1, we get y=2(1)+3=5, meaning that when x=1 the line is at (1,5). Since the line cannot be at (1,5) and (1,4) at the same time, (1,4) is not on the line.
