1.

We have X and Y variables in the dataset which have a corrrelation of 0.75

X Y
123 112
178 214
116 156
119 123
125 114
154 222
140 168
104 165
164 234
152 143
150 170
158 201
168 267

This correlation is positive, which means that if X increases, Y increases. If X decreases, Y will decrease. Please note that correlation doesn't imply causality

2.

We have X and Y variables in the dataset which have a corrrelation of -0.89

X Y
156 23
231 12
47 156
24 167
134 101
8 305
45 168
45 203
5 289
2 343
34 201
43 187
45 250

It means that the correlation is negative, i.e. if X increases, Y decreases. Also, a correlation of -.89 means it is a linear correlation of good strength. Correlation doesn't imply causality
