Answer: C:10
Step-by-step explanation:
Equation of a line passes through (a,b) and (c,d) :
Equation of line passes through A(-2,8) and B(4,14) will be :
For y-intercept , put x= 0 , we get y= 10
So, the y-intercept = 10
Thus , correct option = C:10
ANSWER
The solution set is (4,6)
EXPLANATION
The first equation is
The intercepts are:
(0,18) and (6,0).
We plot the intercepts and draw a straight line through them.
The second equation is,
This equation also passes through,
(0,0) and (1,1.5).
We plot this point too and draw a straight line through them.
The two straight lines intersect at (4,6).
See graph.
Hence the solution set is (4,6).
