I'm struggling fr now, pls can you help me answer these questions using the y= mx+ c method thanks!
Phoenix [80]

Answer:

Examination of the equation shows (graph):

x = 0, y = .5

Then .5 = c      gives us the value of c giving

y = m x + .5    is our equation

Using y = 0, x = -1 gives

o = -1 * m + .5

m = .5

y = .5 x + .5    for the final equation

Check:

At x = 5, y = 3

3 = .5 (5) + .5 = 3
