Im not good at math
Step-by-step explanation:
Answer:
41/25
Step-by-step explanation:
Answer:
1. y = -10x + 6
2. y = -x - 6
3. y = 13x + 110
4. y = -5x + 47
5. y = 7/4 x -7
Step-by-step explanation:
2. m = - 1 and Y-intercept: -20 - (- 1)(14) = -6
3. m = 13 and Y-intercept: -7 - (13)(- 9) = 110
4. (10,-3) and (7,12)
Slope = (12 - - 3)(7- 10) = 15/-3 = -5
y- intercept = 12 - (-5)(7) = 47
5. (4,0) and (0, -7)
Slope: (-7-0)/(0-4) = -7/-4 = 7/4
y-intercept: -7 - 7/4)(0) = -7
(y - yo) = m.(x - xo)
Let's go
(-1/n - (-1/m)) = s.(1 - n/m)
(-1/n + 1/m) = s.(1 - n/m)
(-m+n)/mn = s.(m - n)/m
If we multiply both sides by m
(-m + n)/n = s.(m - n)
If we take the (-1) from the left side we have
(-1.(m - n))/n = s.(m - n)
And if we divide both sides by (m - n)
-1/n = s
So our slope is -1/n
Answer:
m=9
Step-by-step explanation:
4.5/0.5=0.5m/0.5
9=m
0.5 can go into 4.5, 9 times
