What scale factor was applied to the first rectangle to get the resulting image interior answer as a decimal in the box

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.

Solve - pv + 40 < 65 for v solve 7w - 3r = 15 for r
