How do I find the value of x so the slope of a line through (x,5) and (4,2) is 1/3?

1 answer:

Slope=change in y/change in x
1/3 = 5-2/x-4 (or 2-5/4-x)
1/3 = 3/x-4
then cross multiply
1(x-4) = 3(3)
x-4=9
add 4 to both sides
x=13

Answer:

x = 6

Step-by-step explanation:

these are vertically opposite angles

10x+6 = 11x

so, since only one x is missing from 10x but 6 is addling we can say that x= 6

10 multiplied by 6 = 60

60+6 = 66

11 multiplied by 6 = 66

so by this we can say,

x= 6

Algebra I

Coordinates (x, y)
Midpoint Formula: $\displaystyle (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

Step-by-step explanation:

Step 1: Define

Point (2, 9)

Point (8, 1)

Step 2: Identify

(2, 9) → x₁ = 2, y₁ = 9

(8, 1) → x₂ = 8, y₂ = 1

Step 3: Find Midpoint

Simply plug in your coordinates into the midpoint formula to find midpoint

Substitute in points [Midpoint Formula]: $\displaystyle (\frac{2+8}{2},\frac{9+1}{2})$
[Fractions] Add: $\displaystyle (\frac{10}{2},\frac{10}{2})$
[Fractions] Divide: $\displaystyle (5,5)$

The answer too this??? And how to solve

julia-pushkina [17]

alright then, 12x + 17 = 66! we started with 17 and there is twelve months with x amount of inches grown plus the already 17 that equals the total 66

so it is 12x + 17 = 66
