3* (a + 1,5) = - 1,5 [:3
a + 1.5 = - 0,5
a = - 0,5 - 1.5 = -2
Do you mean like this?
Y = -x - 4
Y = x
x = -x - 4
2x = -4
x = -2
Therefore y = -2
During week 2, he could type 15 words per minute, at his fourth week, he could type 30. So 30-15=15. He could type 15 words faster on week 4 than he could at week 2.
For 16/18 it would be 8/9
For 10/15 it would be 2/3
