find the slope of the line?

Question

i have a graph with a line and it originates from these points (-7,7)
and then possible answers below it
a=-7
b=7
c=1
d--1

Answer 1

So are you saying that each y-coordinate is 7? Without the y-coordinate, you can't figure out the slope of a line...unless you already have the equation for the line. Then all you have to remember is that

y = mx + b

m = the slope, and b = the y - intercept

Answer 2

You only have ONE point. It takes 2 to determine a straifht line. With only 1 point, a line of any slope can pass through it

Answer 3

You said THESE points but you only listed one.

Answer 4

.........................................and ur answer is c , i.e., 1
ur line makes an angle of 45 degrees with positive x-axis and tan45 is 1
