Assuming 0x6A is given in base 16, first convert 
and 
to a common base, say base 10:
Then
Step-by-step explanation:
112+68+112+x = 360⁰
292⁰+x = 360⁰
x = 360⁰- 292⁰
x= 68⁰
To graph y=-7x-3, you're going to make your first coordinate at (-3,0) b/c that is your y-intercept and you will continuously move down 7 and right one.
To graph y=4, you will simply make a horizontal line through the to coordinate (4,0).
Hope that helped.
