Answer:
A
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 = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (1, 1)
m = = - 2
note the line crosses the y- axis at (0, 3) ⇒ c = 3
y = - 2x + 3 → A
Answer:
Their sides must be in the same ratio and their angles must be equal.
Step-by-step explanation:
If two polygons are similar their sides must be in the same ratio and their angles must be equal.
e. g. -
If ABCDEF and GHIJKL be the two polygons,
then,
and,
∠ABC = ∠GHI ; ∠BCD =∠HIJ ; ∠CDE = ∠IJK ; ∠DEF =∠JKL ; ∠EFA =∠KLG;
∠FAB = ∠LGH .
Consider the given equation is and one of the 6 in the options is -6.
Given:
The equation is
To find:
The value of x.
Solution:
We have,
Subtracting 3 from both sides, we get
Divide both sides by -2.
Therefore, the value of x is -6.
