Answer:
y = x +
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 ) = (4, 6)
m = = , thus
y = x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (4, 6 ), then
6 = + c ⇒ c = 6 - = =
y = x + ← equation of line
Answer:
points are( 6,2),(7,5) and (3,8)
Step-by-step explanation:
X,y changes into y,-X
Answer:
c
Step-by-step explanation:
Multiplying 49 by 1/7 in the inverse operation of dividing it by 7, so they will both get the correct answer.
