Answer:
the slope is 4/1 because it's 4x and the y intercept is -4
Y=mx+b
mx=slope
b=the y intercept
y= value of y in this equation
A relation is a function if it passes the vertical line test. That graph in a coordinate plane is just a sin wave that is spread out. If you run a perfectly vertical line through the graph at every place on the graph, the line you draw will only go through the graph at one place every time. That makes it a function. It's not a one-to-one function cuz it fails the horizontal line test, but it is a function!
So you cannot really get the exact measure because they didn't give you any measures, but we can infer that if c>b and a then
maybe SX (d) is more than b and a so
a<b<c or d not sure which
sorry if I didn't help
