Answer:
Part A: a. the point 3 units to the left of 7
Part B: b. -4
Step-by-step explanation:
Part A: The expression can be simplified into 7 - 3, and when you subtract a number, you go left on the number line, so the point 3 left of 7
Part B: 7 - 3 = 4, and to get to 0 from 4, you need to subtract 4 or add -4
Which one?
Go to www.mathpapa.com and put this in "<span>y = <span><span>−<span>2x </span></span>− 4</span></span>; <span>y = <span><span>2x </span>− <span>4" That is 1st
</span></span></span>For 2nd put this in "y = 1/2x + -11/2; y = -2x + 2"
Length = √(y2-y1)² + (x2-x1)²
l = √(8-8)² + (7+3)²
l = √10²
l = 10
In short, Your Answer would be 10 units
Hope this helps!
