Answer:
-7.2
Step-by-step explanation:
-3 (1.2) 2= -3×1.2×2
-3×1.2×2
-3.6×2
-7.2
-3 (1.2) 2= -7.2
Hi There!
Solution,
Point Slope Form: y - y1 = m(x - x1)
Now you have a reference equation of what the answer should look like.
By looking at the answer choices you can eliminate A.
Tip: When you have a negative number you are going to add. For Example, if you have -8, you will input x + 8 or y + 8.
Tip 2: When you have a positive number you are going to subtract. For Example, if you have 3 you will input x - 3 or y - 3.
We can eliminate B because its not subtracting 3.
We can also eliminate C because its not adding -8.
The best answer choice is D.
Answer,
y – 3 = 6(x + 8)
I hope you understand, so you can do this in the future on your own.
Hope This Helps :)
Slope is rise over run so since it rose 4 and went 1 to the right the slope would be 4 because 4/1=4
P.S. The actual formula for slope is y2-y1 over x2-x1 so it would be 5-1/1-0 which again is 4/1
