Y = 7x + b
2 = 7 + b, b = -5
Y = 7x - 5

Answer:
E = (-14, 15)
Step-by-step explanation:
The midpoint relation is ...
M = (D +E)/2
2M = D +E . . . . multiply by 2
E = 2M -D . . . . subtract D
E = 2(-4, 8) -(6, 1) = (-8-6, 16 -1)
E = (-14, 15)
Point slope form:
(y-y1) = m (x-x1)
m=slope=1/2
given point (x1,y1) = (-2,7)
(y-7) = 1/2 (x+2)
slope intercept form:
y-7 = 1/2x + 1
y = 1/2x + 8
ANSWER: y=1/2x + 8
Answer:
37°
Step-by-step explanation:
ΔOPQ extended trough Q to R
m∠PQR = (7x-19)° -is an exterior angle to the triangle
m∠OPQ = (2x-3)° -angle inside the triangle
m∠QOP = (x+16)° -angle inside the triangle
m∠PQR = ?
m∠PQR = m∠OPQ + m∠QOP
7x-19 = 2x-3 +x+16
7x -2x-x = 16-3+19
4x = 32
x=32/4=8
m∠PQR = 7x-19 = 7*8-19 =56 -19= 37°
Y=-3x+ 2
hopefully this is right!
