Using elimination method. Using substitution will cause some fraction problems.
c- child tickets
a- adult tickets
4a + 7c = $83
5a + 6c = $90
multiply by -5
-20a - 35c = -$415
20a + 24c = $360
-11c= -$55
c = $5 child tickets
4a + 7(5)= $83
4a + 35 = $83
4a = $48
a= $12 adult tickets
Answer: y + 4 = -3(x+1)
Step-by-step explanation:
We need to rewrite in form of y=mx+b.
3x+y=5
y = -3x + 5
The slope is -3.
In addition, the slope of two parallel line would be equal, the slope of the line would be -3.
y- y1 = m(x- x1)
y- (-4) = -3(x - -1)
y + 4 = -3(x+1)
