Answer:
y = 3x - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (3, 4 ) and (x₂, y₂ ) = (2, 1 )
m =
=
= 3 , then
y = 3x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (2, 1 ) , then
1 = 6 + c ⇒ c = 1 - 6 = - 5
y = 3x - 5 ← equation of line
Answer:
16
Step-by-step explanation:
using the abs value rewrite equation to: 8 + 4(-5 + 9) ÷ 2
8+4(4)/2
8+16/2
8+8=16

Answer:
A = 159.31 ft^2
Step-by-step explanation:
When two solids are similar then the ratio in their surface region is the square of the scale factor of similarity.
please mark me brainliest!
The ratio of the corresponding sides is in the ratio 7:4
The ratio of the areas is 7^2:4^2 = 49:16.
