Answer:
y=3/2 x + 5
Step-by-step explanation:
<em>Firstly, find m (gradient).</em>
m= (y1-y2)/(x1- x2)
m= 8-(-1)/ 2-(-4)
m= 9/ 6
m= 3/2
<em>Please leave gradient in improper fraction if its value is not a whole number.</em>
<em>Now substitute m into the equation:</em>
y= 3/2 x + c
<em>Then substitute a coordinate to find c:</em>
When y= 8, x= 2,
8= 3/2 (2) + c
8= 3 + c
c= 8 - 3 = 5
Thus, the equation of the line is y= 3/2 x + 5.
The width of the rectangle as a function of its length is w = 55/l
<h3>How to find the area of a rectangle?</h3>
The formula for finding the area of a rectangle is expressed as:
A = lw
where
l is the length
w is the width of the rectangle
Given that A = 55 square inches, then;
55 = lw
w = 55/l
Hence the width of the rectangle as a function of its length is w = 55/l

Answer:
8/5
Step-by-step explanation:
(y2-y1) / (x2-x1)
10-2 = 8
8-3 = 5
8/5
I think the answer is A, I could be wrong though
