Advice

Remember that when the equation of a straight line is written in the form $y=mx+c$ , $m$ represents the gradient (or slope) of the graph and $c$ is the $y$ -intercept, the value of $y$ when the graph crosses the $y$ axis.

A positive gradient tells us that the values of $y$ are increasing as $x$ increases so the graph slopes upwards going from left to right. If the gradient is negative, $y$ decreases as you go from left to right.

See http://www.mathcentre.ac.uk/resources/Engineering%20maths%20first%20aid%20kit/latexsource%20and%20diagrams/3_3.pdf for more about straight line graphs.
