Q. What is the slope of the line through (−10,1) and (0,−4)
Identify Coordinates: Identify the coordinates of the two points.Point 1: (−10,1)Point 2: (0,−4)We will use these coordinates to calculate the slope of the line.
Recall Slope Formula: Recall the formula for the slope m of a line given two points (x1,y1) and (x2,y2) 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=−105m=−21
