<h3>
Answer: -1/2</h3>
Work Shown:
Apply the slope formula
m = (y2-y1)/(x2-x1)
m = (1-3)/(3-(-1))
m = (1-3)/(3+1)
m = -2/4
m = -1/2 is the slope
In decimal form, this converts to -0.5, though usually slopes are in fraction form.
F’= 7+2x, plz mark my answer~
The slope of every horizontal line is 0 because that is based on the formula. If it's horizontal on the x axis for example, the point slope will be 0,0, also the horizontal line is the numerator, i think. And the undefined slope is vertical because it's the denominator.
