Answer:

h = -1, j = 3

Step-by-step explanation:

Let's subtract the first equation from the second one:

(2h + j) - (2h - 3j) = 1 - (-11)

2h + j - 2h + 3j = 1 + 11

4j = 12

j = 12 : 4

<u>j = 3</u>

Then let's solve the second equation as we know <em>j</em>:

2h + 3 = 1

2h = -2

h = -2 : 2

<u>h = -1</u>

The points(1,r) and (5,-4) lie on a line with slope 5. find the missing coordinate r. ​
Arte-miy333 [17]

The value of r is -24

Step-by-step explanation:

Given points are:

(1,r) and (5,-4)

Let the points be:

(x1,y1) = (1,r)

(x2,y2) = (5,-4)

m = 5

The slope is given by:

m = \frac{y_2-y_1}{x_2-x_1}\\5 = \frac{-4-r}{5-1}\\5 = \frac{-4-r}{4}\\5 * 4 = -4-r\\20 = -4-r\\20+4 = -4-r+4\\24 = -r\\r = -24

Hence,

The value of r is -24
