Answer:
y = -3x + 7
Step-by-step explanation:
The equation of a line
y = mx + c
y - intercept point y
m - slope of the line
x - intercept point x
c - intercept point of the line
Step 1: find the slope
m = y2 - y1 / x2 - x1
Given two points
( 1 , 4) ( 2 , 1)
x1 = 1
y1 = 4
x2 = 2
y2 = 1
insert the values
m = 1 - 4 / 2 - 1
m = -3/1
m = -3
y = -3x + c
Step 2: substitute any of the two points given into the equation of a line
y = -3x + c
( 1 ,4)
x = 1
y = 4
4 = -3(1) + c
4 = -3 + c
4 + 3 = c
c = 7
Step 3: sub c into the equation
y = -3x + 7
The equation of the line is
y = -3x + 7

The area of a 2D form is the amount of space within its perimeter. The lateral area of the triangular prism is 724.28m², while the total area of the prism is 752.28m². The surface area of the cylinder will be 414 in².
<h3>What is an area?</h3>
The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
A.) The area of the lateral faces are:
Latera area of the triangular prism = (38×7)+(38×8.06)+(38×4) = 724.28m²
The total area of the prism is:
The total area of the prism = Lateral Area + Area of the base face
= 724.28m² + 2(0.5×7×4)
= 724.28m² + 28m²
= 752.28m²
Hence, the lateral area of the triangular prism is 724.28m², while the total area of the prism is 752.28m².
B.) The surface area of the cylinder can be written as,
Surface Area = 2πrl + 2πr²
= (2×π×9×14) + (2×π×9×9)
= 252in² + 162in² = 414in²
Hence, the surface area of the cylinder will be 414 in².
