Solve s=2b+lw for l. Show all work

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.

Put the equation in slope intercept form by solving for y

Can someone me with this? i’m not sure what to put for my equations.
