Answer:
y = - 3x + 7
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 ) = (2, 1) and (x₂, y₂ ) = (5, - 8)
m = =
= - 3 , thus
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 = 7
y = - 3x + 7 ← equation of line
Answer:
14x - 9 + 8x + 3 = 9x - 8 - 3x - 14
Combine like terms:
14x + 8x - 9 + 3 = 9x - 3x - 8 - 14
22x - 6 = 6x - 22
Subtract 6x from both sides:
22x - 6x - 6 = 6x - 6x - 22
16x - 6 = -22
Add 6 to both sides:
16x - 6 + 6 = -22 + 6
16x = -16
Divide both sides by 16:
16x/16 = -16/16
x = -1. There is only one solution to this equation.

Hello! Your answer would be, BELOW
Step-by-step explanation:
A term is a single mathematical expression. It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient.
Term's are 7x and 5
