4x - 5y + 20 = 0
<u> - 20 - 20</u>
4x - 5y = -20
4x - 4x - 5y = -20 - 4x
-5y = -20 - 4x
<u>-5y</u> = <u>-4x - 20</u>
-5 -5
y = ⁴/₅x + 4
The slope would be ⁴/₅.
A number b increased by 3 is greater than or equal to -26:
Example:
If I give u a ratio of the number of teachers to students is 2:1 would mean that for every 2 teachers there is 1 student.
In question 10(a) the ratio of grey to black is 3:1 which means that the percentage would be 33%
In 10 (B) the ratio would be 6:4
