Answer:
y=-4x+4
Step-by-step explanation:
y-y1=m(x-x1)
y-(-4)=-4(x-2)

Answer:
see explanation
Step-by-step explanation:
(a)
a × - b ( cancel 3 and 15 and 7 and 21 )
= a × - b
= - ab
(b)
3xy(5x²y² - 4yz) ← multiply each term in the parenthesis by 3xy
= 15x³y³ - 12xy²z
N= 277
9×27 = 243
2×31 = 62
243+62 = 305
305-28=277
