Ответ:
r = 0
Step-by-step explanation:
We are provided with some information
Slope = 2
Two points = ( 9 , -2)
( 10 , r)
Formula for slope
m = y_2 - y_1 / x _2 - x _1
x_1 = 9
y_1 = -2
x_2 = 10
y_2 = r
Inserting the values
m = y_2 - y_1 / x _2 - x _1
m = r - (-2) / 10 - 9
m = r + 2 / 10 - 9
m = r + 2 / 1
Given m = 2
2 = r + 2 / 1
Cross multiply
2 * 1 = r + 2
2 = r + 2
2 - 2 = r
0 = r
Therefore, r = 0
