Answer:

Step-by-step explanation:

y=mx+b where m=slope and b=y intercept

m=(y2-y1)/(x2-x1)=(22-4)/(0+8)=2.25

y=2.25x+b, using point (0,22) we can solve for b

22=2.25(0)+b

b=22

y=2.25x+22 or stating it fractionally

y=9x/4+22

267 x 0.02 = 5.34
267 + 5.34 = 272.34

267 x 0.08 = 21.36
267 - 21.36 = 245.64


267 + 272.34 + 245.64 = $784.98

Ab and bc form a right angle at point B. if a= (-3,-1) and B= (4,4) what is the equation of BC?
Vesnalui [34]

Answer:

Option C -7x-5y=-48

Step-by-step explanation:

step 1

Find the slope of AB

we have

A(-3,-1) and B(4,4)

The slope m is equal to

m=(4+1)/(4+3)

m=5/7

step 2

Find the slope of BC

we know that

If two lines are perpendicular, then the product of their slopes is equal to -1

so

m1*m2=-1

we have

m1=5/7

substitute

5/7*m2=-1

m2=-7/5

step 3

Find the equation of the line into slope point form

y-y1=m(x-x1)

we have

m=-7/5

B(4,4)

substitute

y-4=-(7/5)(x-4)

Multiply by 5 both sides

5y-20=-7x+28

7x+5y=28+20

7x+5y=48

Multiply by -1 both sides

-7x-5y=-48
