Find the slope of a line through the points (2, 5) and (3, 5).
Find the slope of a line through the points (2,5) and (3,5). We know that line y = kx + b is represented in the slope-intercept form, where k - slope. We can ﬁnd k and b. (2,5) belongs to the line so 5 = 2k + b. (3,5) belongs to the line so 5 = 3k + b. we have that 2k + b = 5 = 3k + b then 2k + b = 3k + b and ﬁnaly k = 0. We get that the slope of the line is equal to 0.
