6/10 = 3/5
Simply divide the numerator and denominator of 6/10 by 2. 6/10 is the same as 3/5.
5t = 25+2r
t = (25+2r)/5 or
t = 5 + (2/5)r
Answer: y = -(9/5)x - 1
Step-by-step explanation:
Rewrite the equation in standard form: y = (5/9)x+(8/9). [y=mx+b]
A line perpendicular to this would have a slope that is the negative inverse of the original slope (5/9), which would make it -(9/5). The y-intercept would also change, but we don't know the value, yet. For now, we'll use "b" for the y-intercept. This results in a perpendicular line:
y = -(9/5)x + b
We can calculate b, the y-intercept, by using the point (-5,8) and solving for b.
8 = -(9/5)*(-5) + b
8 = (9) + b
b = -1
The line perpendicular to 5x−9y=−8 that passes through the point (−5,8) is
y = -(9/5)x - 1
Let m=n-4
n - 4 + 5n = 20
6n = 24
> n = 4
m = 4 - 4
> m = 0
(0,4)
Answer:
line b
Step-by-step explanation:
y = -2x+2 has a slope of -2 (means it's going downhill) and a y-intercept of 2. Line b is the only line that matches this description.
