1.50 that should be it and i dont know how to show my work on a computer SORRY.
252 you multiply the 42 and 12 then devoid even by 2
*******************************
C) y= 7.5x-2
7.5 is a positive slope, and -2 will be your negative y intercept
y=mx+b
Remember m always means slope and b is always the y intercept!
I think it’s the one in the top right? cuz the negative would cancel out the 3x then u would have the 7x • 7x aka 7x to the second power
