Answer:
Slope is 40
Full equation: y=40x-586
Step-by-step explanation:
Slope is y2-y1/x2-x1
14 is x1
-26 is y1
15 is x2
14 is y2
14-(-26)/15-14
40
So the slope is 40
To find the equation
y=40x+b
14=15(40)+b
14=600+b
b=-586
Equation:
y=40x-586
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
