Answer:
C
Step-by-step explanation:
so the y-int is where the point is on the y-axis (0,X). Or, in this situation-2.
for slope, you just need to do rise over run, or up and down first then, left and right. If I do that for C, I go 2 up and 3 right. So the slope os 2/3 (P.S. up and right is positive, and down and left is negative)
1054 (9-8x)=78
(9-8x)= (78÷1054)
9-8x = 0.074
-8x=0.074-9
-8x=-8.926
x= (-8.926÷-8)
x= 1.1157
Nr B:
x = -7 +/- √(-64)
x = -7 +/- 8*√-1
x = -7 +/- 8i
