The y-intercept is the point at which a linear equation crosses the y-axis on the x=0 plot point. The equation to determine both the slope and the y-intercept of a line is y=mx+b. This calculation may ...
If we are given equation of the line instead of the graph, we can still determine the gradient. Equations of straight-line graphs are given in the form: \(\text{y = 2x - 1}\) The gradient is 2 and the ...
