Answer:

\displaystyle y = \frac{1}{4}x - 1

Step-by-step explanation:

1 = ¼[8] + b

2

\displaystyle -1 = b \\ \\ y = \frac{1}{4}x - 1

* Perpendicular Lines have OPPOSITE MULTIPLICATIVE INVERSE <em>RATE OF CHANGES</em> [<em>SLOPES</em>], so −4 becomes ¼.

Find the slope please
Katarina [22]

Answer:

slope is -\frac{3}{4}

Step-by-step explanation:

1,-1  -3,2 are two points on the graph

the equation to find slope is \frac{y_{1}- y_{2} }{x_{1}- x_{2} }

so \frac{2--1}{-3-1} = -\frac{3}{4}

or you can count how many places it changed in the equation \frac{rise}{run}

Here are the equations for 4
Kipish [7]

Answer:

Please see attached graph.

Step-by-step explanation:

The equations for straight lines are given as:

i) y = x +4

ii) y= x-4

Yon can form a table for values of x and y that are true for an equation and use these values as coordinates ( x,y ) to plot the graphs and view the lines to select the correct labels for the equations.  

For i)

y= x+4

x       y      coordinates

-3       1          (-3,1 )

-2        2         (-2,2)

-1         3          (-1,3)

0          4         ( 0,4)

1           5          ( 1,5)

2           6         ( 2,6)

3            7         ( 3,7)

Plot the points on a graph tool and draw the line. Do the same for the second equation to view both graphs as shown in the attached graph.

Which of the following sets could be the sides of a right triangle?
Genrish500 [490]

Answer:

None of the above

Step-by-step explanation:

None of the answer choices are even triangles, let alone right triangles. The sum of the two smaller sides isn't larger than the bigger side on any of the triangles, which means that they cannot be closed.
