A.9/17 = 0,5294117647058824
B.8/45 = 0,1777777777777778
C.17/9 = 1,888888888888889
D.16/90 = 0,1777777777777778
your answer is B and D
Y - 25 = 2(x-10)
y = 2x - 20 + 25
y = 2x + 5. slope = 2
perpendicular lines, slope is opposite and reciprocal
so slope of perpendicular line is -1/2
passing thru (-3, 7)
point slope form: y - y1 = m (x - x1)
equation
y - 7 = -1/2(x + 3)
answer
B. y - 7 = -1/2(x + 3)
Answer:
y=3x+5
Step-by-step explanation:
Point slope equation:
y=mx+b
m-slope, b- is y-intercept
equation given 2 points
y-y1 = m(x-x1)
For point (1,8) and slope m=(y2-y1)/(x2-x1) = 20-8/5-1=12/4=3
y-8 =3(x-1)
arange it in point slope format
y-8=3x-3
y=3x-3+8
y=3x+5
