Graph the equation using the point and the slope.
Alekssandra [29.7K]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have the equation of the line in point slope form

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

where

the point is (5,5)

the slope is m=1/5

Remember that

The formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)

so

<em>To graph the line</em>

1. Plot the point (5,5).

2. From that point, count right 5 units and up 1 unit and plot a second point.

3. Draw a line through the two points

so

The new point is (5+5,5+1) ----> (10,6)

Plot the points (5,5) and (10,6) and draw a line through the two points

The graph in the attached figure

39. Solve for x. SHOW ALL WORK FOR FULL CREDIT m n 6x-4 112°​
coldgirl [10]

Answer:

x = 12

Step-by-step explanation:

6x - 4 and 112 are same- side interior angles and sum to 180° , that is

6x - 4 + 112 = 180

6x + 108 = 180 ( subtract 108 from both sides )

6x = 72 ( divide both sides by 6 )

x = 12
