Answer:
The slope is -0.5 or -1/2
Step-by-step explanation:
the slope of a line is easily calculated by hand using small, whole number coordinates. The formula becomes increasingly useful as the coordinates take on larger values or decimal values.
It is worth mentioning that any horizontal line has a gradient of zero because a horizontal line has the same y-coordinates. This will result in a zero in the numerator of the slope formula. On the other hand, a vertical line will have an undefined slope since the x-coordinates will always be the same. This will result the division by zero error when using the formula.

Answer:
y = -3x -1
Step-by-step explanation:
We can write the equation in slope-intercept form if we know the slope and the y-intercept.
The slope is ...
m = "rise"/"run" = (change in y)/(change in x)
We can see that the line passes through grid intersections at (x, y) = (0, -1) and at (1, -4). Between these two points, the change in y is (-4 -(-1)) = -3, and the change in x is (1 -0) = 1. Then the slope is ...
m = -3/1 = -3
One of the points we just used is the point where the line crosses the y-axis, at the y-intercept of -1. So, with slope -3 and y-intercept -1, the equation of the line is ...
y = mx +b . . . . . . slope m and y-intercept b
y = -3x -1
