Question 1.
First solve for slope:

Point-slope formula is:

where m = slope.
Plug in values for PS form:

So the answer is Choice 2.
Question 2.
Choice D.
Points given: (-10, -7) and (3, -7)
Both y -intercepts are equivalent to -7
Question 3.
Choice A.
Points given: (2, 4) and (2, -7)
Both x - intercepts are equivalent to 2
Answer:
2080
Step-by-step explanation:
The solution to these equations might best be found using Cramer's Rule. It tells you ...
x = (56939×3 -41655×2)/(-236×3 +838×2) = 87507/968 ≈ 90.400
This is years after 1990, so the year the incomes become the same is predicted to be ...
1990 +90.4 = 2080.4
The median incomes will be the same in the year 2080.
im assuming the 4 is an exponent, so (2 * 3 * 7)^4 = 2^4 + 3^4 + 7^4 because of the distributive property. the ^4 gets distributed to everything inside of the parentheses.
The second answer is correct
Because the point is on 1 and it moved 3 steps but to the left hand side as it is (-3) So it’s going to land on (-2)
