Answer:
y = - 3x + 11
Step-by-step explanation:
the altitude is a line from the vertex A drawn perpendicular to the opposite side BC
calculate the slope of BC using the slope formula
m =
with (x₁, y₁ ) = B (- 7, 3 ) and (x₂, y₂ ) = C (- 1, 5 )
= = = =
given a line with slope m then the slope of a line perpendicular to it is
= - = - = - 3
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept ) , then
y = - 3x + c ← is the partial equation
to find c substitute A (4, - 1 ) into the partial equation
- 1 = - 12 + c ⇒ c = - 1 + 12 = 11
y = - 3x + 11 ← equation of altitude from A
P= (intrest)rate(time)
so t equals time
The new coordinates of C' are (3', -4)
<h3>What are the new coordinates of C'?</h3>
The statement is given as:
Point C (3, -4) is reflected over the y-axis.
The rule of reflection over the y-axis is
(x, y) = (-x, y)
So, we have:
Point C = (3, -4)
This means that:
Point C' = (3', -4)
Hence, the new coordinates of C' are (3', -4)
