Answer:

y = 8x + 0

Step-by-step explanation:

y = mx + b

m is slope

slope = change in y / change in x = (24 - 8) / (3 - 1) = 16/2 = 8

so equation is now y = 8x + b

Substitute any coordinate from the table to find b. let's use (1,8)

y = 8x + b

8 = 8(1) + b

0 = b

So equation is y = 8x + 0

When we multiply the polynomials we will get:
(5x^2+2x)(3x^2-7x+4)
=5x^2(3x^2-7x+4)+2x(3x^2-7x+4)
=15x^4-35x^3+20x^2+6x^3-14x^2+8x
=15x^4+(6x^3-35x^3)+(20x^2-14x^2)+8x
=15x^4-29x^3+6x^2+8x
