5. Explain your answer to question 4


I know the pictures aren't there but i really need help :)

Answer 1

What type of graph are you dealing with? This really can't be solved without the graph. However, this may help:

1. A graph represents a linear relationship when the function varies linearly with the variable, that is, when the graph is a straight line.

2&3. The slope of a line is the tangent of the angle it makes with the x-axis. Do the lines make different angles with the x-axis or not? Which one makes a larger angle if the two are different?

4&5. A solution can be considered as a point where the graph meets the x-axis (y = 0).
