Answer:
y=0.3x - 7.6
Step-by-step explanation:
line: y=ax+b
a= Δy ÷ Δx
a= (-9 + 7) ÷ (-5 - 2)
a= -2 ÷ -7 = approximately 0.3
y=0.3x + b
Now you can fill in one of the points to find b (or both to make sure you got the answer right).
0.3 × 2 + b = -7
0.6 + b = -7
b = -7 - 0.6 = approximately -7.6
So: an equation of the line that passes through this pair of points is y=0.3x - 7.6
On a test, i would write as many decimals as possible if not said not to, to get the most exact answer. Also remember to keep calculating with the number on your calculator and not to round them off for the most exact answer.
Answer:
75 degrees
Step-by-step explanation:
1. Find angle J.
The outside angle and angle J are supplementary, which means they add up to 180 degrees.
180 - 130 = 50.
So angle J is 50 degrees.
2. The angles in a triangle add up to 180. Add up angles J and K and subtract that from 180
50 +65 = 105
180- 105 = 75
so did you get what I solved the answer is D ok
