Find the value of r so the line that passes through the pair of points has the given slope.

SOVA2 [1]

Answer:

The missing value in the ordered pair is 66

Step-by-step explanation:

Given that:

(12,10) and (-2,r)

Slope = m = -4

We have to find the value of r so that the line has a slope of -4.

Slope is the steepness of line which is denoted by m.

Here,

$x_1=12, y_1=10\\x_2=-2, y_2=r$

Putting the values in slope of line formula,

$-4=\frac{r-10}{-2-12}\\ -4=\frac{10-r}{-14}\\$

Multiplying both sides by -14

$-4*-14=\frac{r-10}{-14}*-14\\56=r-10\\56+10=r\\66=r\\ r=66$

The value of r is 66

Hence,

The missing value in the ordered pair is 66
