The slope is -2 because y = mx + b

y-y₁ = m (x-x₁)

y - 3 = -2 (x-0)

y - 3 = -2x

y = -2x + 3

What is the slope of the line joining (8,8) and (12, 6)?

Anna71 [15]

Answer:

$\huge \boxed{ \boxed{ - \frac{1}{2} }}$

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

$m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\$

From the question we have

$m = \frac{6 - 8}{12 - 8} = - \frac{2}{4} = - \frac{1}{2} \\$

We have the final answer as

$- \frac{1}{2} \\$

Hope this helps you

What is the x-coordinate of the point that divides the directed line segment from J to K into a ratio of 2:5?

Marianna [84]

Answer:

Second option is correct. The x-coordinate of the point that divides the directed line segment from J to K into a ratio of 2:5 is -2.

Step-by-step explanation:

From the given graph it is noticed that the endpoints of the line segment JK are J(-6,-2) and K(8,-9).

The formula to find x intercept.

$x=\frac{m}{m+n}(x_2-x_1)+x_1$

The ratio is 2:5, therefore the value of m is 2 and the value of n is 5.

$x=\frac{2}{2+5}(8-(-6))+(-6)$

$x=\frac{2}{7}(14)-6$

$x=4-6$

$x=-2$

Therefore the x-coordinate is -2 and second option is correct.

A student's course grade is based on one midterm that counts as 20% of his final grade, one class project that counts as 5%

Ludmilka [50]

Answer:

Step-by-step explanation:

The weighted average of the student's scores is ...

0.20×63 +0.05×97 +0.35×85 +0.40×77 = 78

The student's overall final score is 78.

The letter grade earned is between 70 and 80, so is a C.
