Afreight train and an express train leave towns 390 miles apart at the same time, traveling toward one another. the freight train travels 30 mph slower than the express train. they pass one another 3 hours later. what are their speeds?

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.

The line y = x + passes through (−3, 7) and is parallel to y = 4x − 1.
