The slope between two points A and B is given by the formula:
Replace the coordinates of the given points (1,1) and (-4,-3) to find the slope between those two points:
Plot the points (1,1) and (-4,-3). Then, draw the line through them:
Notice that the line goes up by 4 units for each 5 units that it goes to the right. This confirms that the slope is 4/5.
Therefore, the value of the slope of the line that passes through the points (1,1) and (-4,-3) is 4/5.
