to find the area of a rectangle is LxW=A
plug in the given numbers you have
L = 7
W = x-8
A = 42
7 * x-8 = 42
7x-56= 42
solve for X
Answer:

Answer:
<h3>y = 1</h3>
Step-by-step explanation:
Correct question
The points ( 2,4) and (5,y) lie on the same line. If the slope of the line is --1, what is the value of y
The formula for calculating slope of a line is expressed as;
m = y2-y1/x2-x1
Substitute the given point
y - 4/5-2 = -1
y-4/3 = -1
y-4 = -3
y = -3+4
y = 1
Hence the value of y is 1
