Point-slope form: we need a point (x₀,y₀) and the slope "m".
y-y₀=m(x-x₀)
Data:
(1,1)
m=2
Therefore:
y-y₀=m(x-x₀)
y-1=2(x-1) This is the equation of the line in point-slope form.
Answer. y-1=2(x-1)
Answer:
It's 21
Step-by-step explanation:
12/16 = x/28
cross multiply
16x = 336
divide by 16 on both sides
you get x = 21

Step-by-step explanation:
If the bottom number is the same thing as 1 then it will be 1, if not, then it will be a mixed fraction
Answer:
A. x = -3
B. x = 2
C. x = 9/10
Step-by-step explanation:
(A) –12x + 9 = –15x
Collect like terms
9 = -15x + 12x
9 = -3x
x = 9 / -3
x = -3
(B) 4.5x + 11.5 = 8.5x + 3.5
4.5x - 8.5x = 3.5 - 11.5
-4x = -8
x = -8 / -4
x = 2
(C) 23x – 9 = 13x
-9 = 13x - 23x
-9 = -10x
x = -9 / -10
x = 9/10
