Answer:21
Step-by-step explanation:
Answer:
y = 17.5
Step-by-step explanation:
Given that 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 y = 35 when x = 140, then
35 = 140k ( divide both sides by 140 )
0.25 = k
y = 0.25x ← equation of proportion
When x = 70, then
y = 0.25 × 70 = 17.5
Answer:
1: y intercept = 5
2: y interpcept = -2
3: y intercept = -3
Step-by-step explanation:
So for the 1st and 3rd ones (the graphs), all you have to do is find which y matches the x value of 0
The 2nd one is a bit harder. I’ll explain it the best I can
So in the y section, you see that -4 goes to -3 when the x is raised by 1. There for everytime the x raises by 1, so does the y. That means when x = 0, the y = -2
An equation with a difference of 6 would be 12-6=6
