Please answer the questions below. I really need help with these problems. Thank you.

1.One way to find theformula of a line passing through (10, 11) and (20, 17)

is by using a table, as shown below.Complete parts(a)and(b)below.

(a)Complete thebox inthefirstrow.

xy

0 6

10 11

20 17

(b)Report the formula of the line in slope-intercept form.

y=?x+?

2.Consider the liney= ?2x+ 4.

(a)Find the equation of the line perpendicular to the liney= ?2x+ 4 through the point (?3, 2).

y=

(b)Find the equation of the line parallel to the liney= ?2x+ 4 through the point (?3, 2).

y=

3.The table shows the distance, in miles, that a person is from home.

y=

6.Find the zeros off(x) = 1760x? 11x2.

Do not round your answers.

Report multiple solutions separated by asemicolon, and in increasing order.

Do not include "x=" in your answer.

7.When the polynomial (10x+ 4)(7x2+ 7x+ 2) is expanded, simplified, and written indescending powersofx, we have the expression below. Complete the boxes to report the first and last terms of the expanded polynomial.

(10x+ 4)(7x2+ 7x+ 2) =+98x2+ 48x+

8.Find the zeros off(x)=x²?4x+3

by factoring.

9.Solve the following equations. Enter the zeros separated by semicolons.

For example, if the zeros were 1 and 3 you would type1;3.

(a)(x? 6)(x+ 3) = 0

x=

(b)(x? 6)(x+ 3) = 22

x=
