How do you solving the solution of each system using elimination?

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.

Which equation expression the relationship between the number of boxes b and the number of cans c and the proportion is 48
