Usually this form is described as y mx b form. The slope of a line is the ratio of the amount that y increases as x increases some amount. The line is less steep and so the Slope is smaller.
Slope is a ratio that includes how y changes for every unit increase of x.
Now let us recall the definition of slope in order to be clear as to what are we supposed to find. We can recall that slope is the change in y coordinate with respect to the change in x coordinate of that line. Slope y2 - y1x2 - x1 Slope rise over run. A graphical depiction is shown below.
