So first of all, know that perpendicular lines have slopes that are a negative reciprocal from each other. So your original equation is in slope-intercept format: y = mx + b, where m = slope
So your slope is -1/9. Now the negative of that would be --1/9 = +1/9. Now the reciprocal of 1/9 is 9/1 = 9 (you just flip the fractions ;).
Now that we have our new slope, let's make an equation of a line with that new slope and the point (1, 7). For that let's switch to the point-slope format: y-k = m(x-h), where h = the x-value and k = the y-value.
Our h = 1 and k = 7
y-7 = 9(x-1)
Slope = 3
(-5, 8)
y - 8 = 3 (x + 5)
this is point slope form
y - 8 = 3x + 15
y = 3x + 23
Answer:
3/4
Step-by-step explanation:
3/14 ÷ 2⁄7
Copy dot flip
3/14 * 7/2
We rewrite
3/2 * 7/14
Canceling a 7 from 7 and 14
3/2 * 1/2
Multiplying straight across
3*1 =3
2*2=4
3/4
Answer:
88
Step-by-step explanation:
arrange the marks in ascending order
range = highest value - lowest value
= 99 - 11
= 88
