Answer:
Step-by-step explanation:
y=mx+c
where m is the gradient (or slope of the line) and c is the intercept with the y-axis. The gradient m and c are constants,unlike x and y which are variables; how does this work? The m and c values are fixed to some values, for example m=2 and c=-3 defines the straight line
y=2x-3
x and y are variables which in practice means we pick a value of x and then calculate the value of y ( y is a function of x since it's value depends on x). This process is shown below, where a random x value is selected and is put through a function to calculate the y-value, the coordinate (x,y) is then plotted on the graph. The process is repeated many times; and eventually if you wait l
