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.

Answer:
Perimeter = 10 cm
Area = 6.25 cm²
Step-by-step explanation:







So to find the Perimeter of the square, we'll use this formula :





Hence, the perimeter would be 10 cm .


We know that the formula of Area to find the square is,

Note : The answer would always be in cm².





Hence, the area of the square would be 6.25 cm².
<em>We are done !</em>
