Answer:

The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.

Answer:

change in buyer tastes.

Step-by-step explanation:

Buyers now want more donuts than the other goods.

increase in the cost of donuts is more likely to decrease the amount of donuts consumed, as they would be more expensive

consumers expecting something doesn't necessarily change anything, as they haven't yet dropped and therefore it's unlikely they'd increase the demand until they actually were cheaper.

Coffee doesn't necessarily effect donut sales, unless stated in the question.

Which is an equation of the line that passes through the points (-6, 3) and (2, 7)?

Answers

Answer:

slope: 1/2

y: intercept: (0;6)

so B

The equation of the line is y = x/2 + 6 which passes through the points (-6, 3) and (2, 7) option (B) is correct.

What is a straight line?

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

It is given that:

The line that passes through the points (-6, 3) and (2, 7)

The equation of the line:

y - 7 = (7 - 3)/(2 + 6)[x - 2]

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

y = (1/2)x - 1 + 7

y = x/2 + 6

Thus, the equation of the line is y = x/2 + 6 which passes through the points (-6, 3) and (2, 7) option (B) is correct.
