Answer: x= -9/19
Step-by-step explanation:
5x+18/8=x/4
5x+ 9/4=x/4
5x+9/4-9/4=x/4-9/4
5x= x-9/4
5x(4)=x-9/4(4)
20x=x-9
20x-x=x-9-x
19x=-9
19x/19=-9/19
x=-9/19
It will increase by 5/9 of a degree.
If you convert the given equation into slope intercept form, you will have:
c = (5/9)f + 160/9
In this form, it is easier to see the slope. The line would be increase by a rate of 5/9.
