You get it by subtracting 5 and -1 and dividing it by 3-0 so 632. To find the slope of an equation given in ymxb balance the equation until y is by itself without any constants. Eliminate the slope not plus handicaps altogether.

They literally just need to flip the slope equation and it makes perfect sense. Y 5x - 4. The slope of a linear regression line is the vertical distancethe horizontal distance between any of the two points on this line. The formula for finding the slope of a line on a coordinate plane is y2 - y1 x2 - x1 where x2 y2 and x1 y1 represent two distinct points on the line.
