Line a is parallel to line b. If the measure of angle 2 is 78 degrees, what is the measure of angle 5?

Find the equation of the line that goes through the points (4, –1) and (2, –5). use slope formula, equation, to find the slope of a line that passes through the points. m = use slope-intercept form, y = mx + b, to find the y-intercept (b) of the line. b = write the equation in slope-intercept form, y = mx + b.
