Q. What is the slope of the line through (−10,1) and (0,−4)? Simplify your answer and write it as a proper fraction, improper fraction, or integer. _____
Identify Coordinates: Identify the coordinates of the two points.The first point is (−10,1), which means x1=−10 and y1=1.The second point is (0,−4), which means x2=0 and y2=−4.
Recall Slope Formula: Recall the formula for the slope m of a line through two points (x1,y1) and (x2,y2). The formula is m=x2−x1y2−y1.
Substitute Coordinates: Substitute the coordinates of the two points into the slope formula. m=0−(−10)−4−1
Perform Subtraction: Perform the subtraction in the numerator and the denominator.m=(−4−1)/(0+10)m=(−5)/10
Simplify Fraction: Simplify the fraction to find the slope. m=−21
