Ok so the formula for point-slope is:

m=slope
y1 = y point that's given
x1 = x point that's given
The problem says "use the point (-1,-4)"
so we will put it into our equation.
(-1,-4)
-1 is our x, and -4 is our y, now we can put it into the equation.

Now we need to find the slope using:

y2=4
x2=3
y1=-4
x1=-1
m=2
So the answer is..

Answer:
f(x) = 4(x - 8)
4 (10 -8) = 8
Step-by-step explanation:
Using subUsing substitution for Y, the top equation becomes X +6z= 180. Using elimination with X +6z= 180 and subtracting X+z= 90 result is 5z=90 and Z= 18. So complimentary angle is 18°
Answer:
Y= X - 31.5
Step-by-step explanation:
find the gradient then the equation
Answer:
D. 1.38
Step-by-step explanation:
To compare numbers, start with the left side.
You are comparing these numbers with 1.32:
A.1.02
B.1.23
C.1.31
D.1.38
Start with the leftmost digit, the 1. All numbers start with 1, so up to the units place, they are all the same. See below.
1.32
A. 1.02
B. 1.23
C. 1.31
D. 1.38
Now compare the next digit which is the tenths place.
1.32
A. 1.02
B. 1.23
C. 1.31
D. 1.38
Above, the number 1.32 has a 3 in the tenths place. 3 is greater than 0 and than 2, so options A and B are less than 1.32 and are eliminated.
1.32
C. 1.31
D. 1.38
Now we compare the digits in the hundredths place shown just above. 2 is greater than 1, but it is less than 8, so we eliminate option C.
Answer: D. 1.38
