Find the slope of the given points (2,5) and (8,-3) and write the equation

max2010maxim [7]

Answer:

Slope = $\frac{-4}{3}$

4x + 3y = 23

Step-by-step explanation:

slope = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{-3-5}{8-2} =\frac{-8}{6} =\frac{-4}{3}$

The equation:

$\frac{y-y_{1} }{x-x_{1} }=m$ m is the slope

$y-y_{1}=m(x-x_{1} )$

y - 5 = -4/3 (x - 2) Multiply both sides by 3

3y -15 = -4 (x - 2)

3y - 15 = -4x + 8

3y + 4x = 8 + 15

3y + 4x = 23

4x + 3y = 23

One bag of Roland fertilizer covers 2346 square feet of lawn. How many total bags of fertilizer must be purchased to cover a law

Ivenika [448]

If I did my math correct it should be 47. If you take 284x386 you get 109,624 (that should be the area in square feet) then take 109,624 and divide it into 2346 and you get 46.7280477408. In order to cover it you should round up to 47 bags.
