the correct answer is option c. 3
step-by-step explanation:
points to remember
equation of the line with coordinates (x₁, y₁) and (x₂, y₂) is given by,
slope m = (y₂ - y₁)/(x₂ - x₁)
from the figure we can see a line with two coordinates given
to find the slope of given line
here (x₁, y₁) = (-1, -1 ) and (x₂, y₂) = (1, 5)
slope m = (y₂ - y₁)/(x₂ - x₁)
= (5 - -1)/(1 - -1)
= (5 + 1)/(1 + 1)
= 6/2 = 3
therefore the correct answer is option c. 3
