the y-intercept, b, is 7

Step-by-step explanation:

Compare the given y = -3.1 +7 to y = mx + b. I must assume that you meant

y = -3.1x +7. It becomes evident that the slope, m, is -3.1 and the y-intercept, b, is 7.

$\frac{1}{2}$

Step-by-step explanation:

Given a quadratic equation in standard form

ax² + bx + c = 0 , then the sum of the roots is

α + β = - $\frac{b}{a}$

Here 2x² - x - 3 = 0 is in standard form

with a = 2 and b = - 1 , then

sum of roots = - $\frac{-1}{2}$ = $\frac{1}{2}$
