Answer:
y = - 2x + 13
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, 7) and (x₂, y₂ ) = (5, 3)
m = = = - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (3, 7), then
7 = - 6 + c ⇒ c = 7 + 6 = 13
y = - 2x + 13 ← equation of line

Answer:
x = 12
Step-by-step explanation:
their the same length so plug em equal to each other
x+5 = 2x-7
add 7 to both side to get x+12 = 2x
subtract x from both side to get x = 12
