Underline the correct pronouns(s) in each sentence.
Aloiza [94]

Answer:

1.) Us

2.)  Me

3.) I

4.) Him

5.) Me

6.) She

7.) Her

8.) She and he

9.) Me

10.) Me

Step-by-step explanation:

Let's just say you're confused about which is which-- I or me, he or him, she or her, they or them. For example, #3, Let's say you used "You and me will finish it today". Just omit the first person mentioned and see how it sounds. If you said, “Me will finish it today,” it sounds wrong.

Without two people, it is easier to use your ear to hear if I or me is grammatically correct.

Y=mx+b is equation form.

Step 1: Calculate slope

Slope= y2-y1/x2-x1
Choose 2 points (8,7) and (0,1)
Apply slope formula: 1-7/0-8=-6/-8=3/4(simplified)
M=Slope
Y=3/4x+B
B=Y intercept: 1

Equation: Y=3/4x+1
