write an equation in the form y= mx+b for the line that has a slope of -5 and contains the point (7,0)

Question

pooja195 · Answer

$$\huge~y-y_1=m(x-x_1)$$
m=slope
(x1,y1)

rhystic · Answer

So 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

anonymous · Answer

so i multiply -5 from 7 will equal -35

rhystic · Answer

right. now solve for b .

anonymous · Answer

how do i solve for b

rhystic · Answer

so 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?

anonymous · Answer

b=-35
