Urgent! fndthe slope of the line graph below

The slope is

Step-by-step explanation:

The straight line passes through

and .

The slope of this line can be found using the formula;

Substitute the coordinates;

simplify;

The slope of given line = -3/5

Step-by-step explanation:

Formula:

Slope of a line passing through (x₁, y₁) and (x₂, y₂) is given by,

slope = (y₂-y₁)/(x₂-x1)

From the figure we can see that a line graph

To find two coordinate on the graph

Fro figure we get,

1)  (x₁, y₁) =  (-1, -1)

2)   (x₂, y₂) = (4, -4)

To find the slope of given line

Slope =  (y₂-y₁)/(x₂-x1) = (-4 - -1)/(4- -1) = (-4 + 1)/(4 +1) = -3/5

Therefore the slope of given line = -3/5

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
