Aline has a slope of -2/3 for a pair of points on the line. find the missing coordinate if the points are (-1,y) and (4,7)

The missing co-ordinate is: (-1,).

Step-by-step explanation:

Given the slope of a line and a point on it, we determine the equation of the line by slope - one point form.

Slope - one point form: (y - y₁) = m(x - x₁)

Where, (x₁,y₁) is the point passing through the line.

Here the slope is and the point (x₁,y₁) = (4,7).

Therefore the equation would be:

y - 7 = (x - 4)

⇒  3y - 21 = -2x + 8

⇒                       2x + 3y - 29 = 0       is the equation of the line.

Now it is given that (-1,y) also passes through the line, this point should satisfy the equation.

⇒ 2(-1) +3y = 29

⇒ 3y = 31  i.e., y =

Therefore, the missing co-ordinate is:   (-1,).

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

answer: 40392

step-by-step explanation:

10098 x 4 = 40392
