Answer: y=1/2 - 3
Step-by-step explanation:
what they want you to find is the slope and y-intercept, and put that into slope-int form, which is y=mx+b. the point that is located on the y intercept is (0, -3), which gives you your b, which is -3. the other point on the graph helps you find the rise/run, or slope, which is m=2/4. simplified is m=1/2. so, y=1/2 - 3
Answer:
see explanation
Step-by-step explanation:
(a)
Given y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition when x = 3, y = 18 , then
18 = 3k ( divide both sides by 3 )
6 = k
y = 6x ← equation of proportion
(b)
(i)
when x = 12 , then
y = 6 × 12 = 72
(ii)
when y = 42
42 = 6x ( divide both sides by 6 )
7 = x
