Answer:
x = 0
y = -3

Explanation:
The first given equation is:
x = 3 + y ............> I
The second given equation is:
21x + 8y = -24 ...........> II

Substitute with I in II and solve for y as follows:
21x + 8y = -24
21(3+y) + 8y = -24
63 + 21y + 8y = -24
29y = -24 - 63
29y = -87
y = -3

Substitute with y in equation I to get x as follows:
x = 3 + y
x = 3 + (-3)
x = 3 - 3
x = 0

Hope this helps :)

Answer:

y = x - 3

Step-by-step explanation:

From the table attached,

Scatter plot given in the graph is correct.

Let the equation of the line passing from a point (x', y') is,

y - y' = m(x - x')

m = slope

Slope of the line passing through two points (x_2,y_2) and (x_1,y_1) is given by,

m = \frac{y_2-y_1}{x_2-x_1}

Therefore, slope of the line passing through the points (11, 8) and (12, 9) will be,

m = \frac{(9-8)}{(12-11)} =1

Therefore, equation of the line passing through (11, 8) will be,

y - 8 = 1(x - 11)

y = x - 11 + 8

y = x - 3
