Use the values of a, b, and c to find the discriminant:
0
I don't know if this is correct
Answer:
No
Step-by-step explanation:
Explanation 1)A vertical line can be represented by the equation x=a, where a can be any number. If you think about it, there is no y in the function, this making it not a function.
Explanation 2) For a line to be a function it has to pass the vertical line test, so you will draw a vertical line through the function and if it touches more than one point then it is not a function. In this case if you draw a vertical line through a vertical line there are an infinite number of places where the lines intercept, so it is not a function.
Answer:
slope of line ax + by = c is -a/b
so, slope of 7x +2y =5 is -7/2
Hope this picture helps! ;) Ignore the stuff around it ($12 or the triangle)
