Find the equation of the line with slope=6 and passing through (8,51). Write your equation in the form y=mx+b.
zzz [600]

Answer:

The answer to your question is: y = 6x + 3

Step-by-step explanation:

Data

slope = m = 6

A (8, 51)

Equation

                 y = mx + b

               (y - y1) = m (x - x1)

               (y - 51) = 6(x - 8)

               y - 51 = 6x - 48

                     y = 6x - 48 + 51

                     y = 6x + 3

Can someone help me please asap
riadik2000 [5.3K]

Answer:

A. 55°

B. 71°

C. 100°

D. 65°

E. 120°

F. 155°

G. 147°

H. 36°

I. 70°

J. 54°

K. 24°

L. 40°

Step-by-step explanation:

A. 180 - (90 + 35) = 55°

B. 180 - (34 + 75) = 71°

C. 180 - (43 + 38) = 100°

D. 180 - 50 = 130 / 2 = 65°

E. 180 - (90 + 30) = 60°

180 - 60 = 120°

F. 180 - (120 + 35) = 25°

180 - 25 = 155°

G. 180 - 145 = 35 + 112 = 148°

H. 180 - (40 + 26) = 144°

180 - 144 = 36°

I. 180 - (60 + 65) = 125°

180 - 125 = 55°

180 - (55 + 50) = 75°

180 - (75 + 35) = 70°

J. 180 - 116 = 64°

180 - (64 + 62) = 54°

K. 180 - (138 +18) = 24°

L. 180 - (80 + 60) = 40°
