Answer:
y = 0.5x + 5
Step-by-step explanation:
Use the slope formula to find the slope of a line given the coordinates of two points on the line.
The slope formula is:
m = =
The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.
Now let's fill in the formula with the points,
m =
Solve,
⇒ Y = 9 – 7 = 2
⇒ X = 8 – 4 = 4
m = =
Simplify,
⇒
Therefore, the Equation of the line is y = 0.5x + 5.
The easiest way is if it doesn't need to be simplified. Multiply -2.105 by 
. You get the fraction 
. While this is technically the answer, you can simplify this down to 
. Because 421 is a prime number, this can not be simplified any further. Therefore, the solution is .
