What is the slope of the line that goes through points (−3,−4) and (−7,16)? please help

The slope of the line will be "-5".

Given points are:

As we know the formula,

→ Slope,

By substituting the values, we get

Thus the above answer is correct.

5

Step-by-step explanation:

slope =

The second y point is 16 and the first is -4, so:

(16) - (-4)

Which can be written as 16 + 4 because a double negative makes a positive. Do the same for the x points, -7 and -3:

(-7) - (-3)

(-7) + (3)

Now solve both of them:

16 + 4 = 20

(-7) + 3 = -4

Remember, the slope formula is y over x, so we still need to put it into the fraction form:

You can reduce this to , or 5.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
