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:
The correct option is A
A) 25 degrees
Step-by-step explanation:
As two parallel line l and m are cut by the line t, the angles formed (x-10)° and < 3 are alternate angles, therefore they are equal to each other.
< 3 = (x-10)° ⇒ Equation (i)
We know that any straight line has a sum of angles equal to 180°.
Consider line t, it is divided into 3 angles due to cutting. Those angles are 85°, (2x)° and (x-10)°. The sum of these angles is 180° as stated before.
85° + (2x)° + (x-10)° = 180°
Find the value of x:
85 +2x + x - 10 = 180
3x + 75 = 180
3x = 105
x = 35°
Substitute it in Equation (i) to get the value of <3
< 3 = (35 - x)°
< 3 = (35 - 10)°
< 3 = 25°
