Not always. For example, try to find the slope of the line that passes through the points (3, 4) and (2, 3).
yes because you will need the slope and y-intercept to find the equation of a line and the point through which the line passes is the y-intercept so it is yes!!!!!!! Good Luck!!!!!!!!!!!!!

slope = change_in_y/change_in_x = (-1 - 2)/(8 - 5) = -3/3 = -1
Slope, m, equals (y2-y1)/(x2-x1). Slope is (8-2)/(8-2) or 1.
It is a straight line with no slope with a 'y' intercept of 2
Slope, m, equals (y2-y1)/(x2-x1). Slope is (0-(-1))/(0-(-1)) or 1/1 or 1.
