Answer:
y + 3 = 2(x + 1)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 2 and (a, b) = (- 1, - 3), thus
y - (- 3) = 2(x - (- 1)), that is
y + 3 = 2(x + 1)
Answer:
y = 56
Step-by-step explanation:
the midsegment SV is half the length of the side TU , that is
y - 9 =
(y + 38) ← multiply both sides by 2 to clear the fraction
2y - 18 = y + 38 ( subtract y from both sides )
y - 18 = 38 ( add 18 to both sides )
y = 56
Expand the right side:


Notice that 98 = 2 * 7 * 7, so we have
and
.
Then
