What is the equation of a line passing through the point (a, b) and having a slope of b?

y = −bx − b(1 − a)
y = bx − b(a − 1)
y=1/bx+b(a-1)
y=-1/bx+b(1-a)

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
