Help pls ill love you forever

Answer:

y-4=\frac{1}{5}(x-7)

Step-by-step explanation:

The point-slope form of a line is given by:

y-y_1=m(x-x_1)

Where

(x_1,y_1) is the coordinate pair (any of the points given)

m is the slope. The ratio of change in y coordinates by x coordinates

Let's calculate the slope:

m=\frac{4-3}{7-2}\\m=\frac{1}{5}

Now, it is given "y - 4", so y_1 is 4, so they are using the coordinate pair (7,4). So we can say x_1 = 7

Now we have all the values, lets write the equation:

y-y_1=m(x-x_1)\\y-4=\frac{1}{5}(x-7)

This is the point-slope form.

HELP ME PLS<br> GRADES ARE DUE TODAY

Answer:

  see attached

Step-by-step explanation:

Most of this exercise is looking at different ways to identify the slope of the line. The first attachment shows the corresponding "run" (horizontal change)  and "rise" (vertical change) between the marked points.

In your diagram, these values (run=1, rise=-3) are filled in 3 places. At the top, the changes are described in words. On the left, they are described as "rise" and "run" with numbers. At the bottom left, these same numbers are described by ∆y and ∆x.

The calculation at the right shows the differences between y (numerator) and x (denominator) coordinates. This is how you compute the slope from the coordinates of two points.

If you draw a line through the two points, you find it intersects the y-axis at y=4. This is the y-intercept that gets filled in at the bottom. (The y-intercept here is 1 left and 3 up from the point (1, 1).)

-4 ≥ x + 2 &lt; 1
Reil [10]
-4 line under > SO -4 > x + 2 < 1

                              (-4 > x + 2) and (x + 2 < 1)


                               (x < -6)  and (x < 1)
     
                                Now combine the ranges

                                x line under < SO 

                                x < -6 is your answer

Brainliest if satisfied!!!
