Best ResponseYou've already chosen the best response.0So you have m in the equation which is the slope. thus you have y = 5x+ b now you need to solve for b. to do this take the y coordinate (0) and plug in to the equation and plug the x coordinate into the equation yielding > 0 = 5(7) + b < now solve for b. then you now can put it back into the form of y = mx + b

Best ResponseYou've already chosen the best response.0how do i solve for b

Best ResponseYou've already chosen the best response.0so you found 35 right which is m*x in the equation y = mx + b you already have 0 for y meaning 0 = 35 + b you now need to isolate b which means b = what?

Best ResponseYou've already chosen the best response.0ok so take out the negative

Best ResponseYou've already chosen the best response.0yes because you need to move the 35 to the other side. Now you have m and you have b so you plug backinto the formula to create the equation. y = mx +b > y = 5x + 35
