My best guess is to go with C, sorry if its wrong!
edit: just realized this said red and blue, my bad!
Answer:
Step-by-step explanation:
Rewrite this quadratic in standard form: 3x^2 + 7x - 1.
The coefficients of x are {3, 7, -1}, and so the discriminant is b^2 - 4ac, or
7^2 - 4(3)(-1), or 49 + 12, or 61. Because the discriminant is positive, this quadratic has two real, unequal roots
This equation defines a line.
.
The y-intercept is (0,4)
.
To find the x-intercept, set y=0 and solve for 'x'.
.
0 = -6x + 4
6x = 4
x = 2/3
which is the point (2/3,0)
.
With two points you can draw a line.
