If a line has a slope of 1/2 and a y-intercept of -6, what is the x-coordinate if the y-coordinate is 4

X=20. Our x coordinate is 20.

Step-by-step explanation:

Based from the given slope of 1/2 and a y-intercept of -6, our equation of a line is y=x/2 -6. To remove the fraction we can multiply the equation by 2 to get 2y=x-12. Using this substitute the value of y coordinate 4.

2(4)= x-12

8+12 =x

X=20.

20

Step-by-step explanation:

since the line has a slope of 1/2, the x coefficient of the line is 1/2. Since the y intercept is -6, we have the equation of the line

x/2 - 6 = y

Since in this case y = 4, we have

x/2 - 6 = 4

x/2      = 10

x          = 20

So the x coordinate is 20 when the y coordinate is 4.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
