In order to graph linear equations by finding intercepts, we must remember what an x and y intercept are. So remember that in an x-intercept it’s the y that equals zero, and for the y-intercept it’s ...
In this graph, π‘₯ and 𝑦 are directly proportional. This means that when π‘₯ doubles, 𝑦 also doubles, and when π‘₯ triples, so does 𝑦. In fact, for all coordinates on this line, you could multiply or ...
Any straight line graph has a constant gradient, which is calculated by the change in 𝑦 divided by the change in π‘₯, along any section of the graph. The gradient is measuring the steepness of the ...
In graphing linear equations by using a t-chart, all we have to do is plug in random values for x and random values for y and get our points that way. So using a t-chart, we are going to draw a chart ...
