How does the value of m affect the graph of the equation?
how does b affect the graph of the equation

We have the slope-intercept form of a straight line given by y = mx + b, where m is the slope and b is the y-intercept.

Now, when the slope m is positive, the straight line will slant upward towards the right and when the slope m is negative, the line will slant downwards to the right.

Moreover, the more positive or negative the slope is, the steeper the slant of the corresponding line will  be.

The change can be seen in figure 1 below where the slope is changing as 2. 4 and -5.

Further, when the y-intercept b is positive, the line will cross the y-axis above the line y=0 and when the y-intercept b is negative, the line will cross y-axis below y=0.

Moreover, the change in y-intercept will shift the graph of the line in left or right direction.

The shift can be seen below in the second figure, where y-intercept changes from 3, 4 and -5.
