1.
the line through the points (10, 7) and (8, –10)
the equation is:
Solved by pluggable solver: FIND EQUATION of straight line given 2 points
hahaWe are trying to find equation of form y=ax+b, where a is slope, and b is intercept, which passes through points (x1, y1) = (10, 7) and (x2, y2) = (8, -10).
Slope a is .
Intercept is found from equation , or . From that,
intercept b is , or .

y=(8.5)x + (-78)

Your graph:





the slope of the line is:

Slope of the line through the points (10, 7) and (8, -10)
















Answer: Slope is





2.
the line through the points (–3, –2) and (–3, 0)

Solved by pluggable solver: Finding the slope


Slope of the line through the points (-3, -2) and (-3, 0)















Since you CANNOT divide by 0, this means that the slope of the line is undefined.


Answer: The slope of the line is undefined.
