Answer:

\boxed{\sf{m=\frac{4}{5}}}

Step-by-step explanation:

In order to solve this problem, we will use the slope.

Slope:

\sf\dfrac{Y_2-Y_1}{x_2-x_1}=\dfrac{rise}{run}

y2=(-6)

y1=(-2)

x2=2

x1=7

Solve the problem by rewriting it down.

\sf{\dfrac{(-6)-(-2)}{2-7} }=\dfrac{(-6)+2}{2-7}=\boxed{\dfrac{4}{5} }

<u>m=4/5</u>

Therefore, the slope is 4/5.

I hope this helps! Feel free to correct me if I am wrong.

Mira picked two numbers from a bowl. The difference of the two numbers was 4, and the sum of one-half of each number was 18. The
kobusy [5.1K]

Answer:

20 and 16

Step-by-step explanation:

Let us find x and y.

x – y = 4 _____(1)

x/2 + y/2= 18___(2)

Multiply (2) by 2 and add to (1)

  x - y = 4

+<u>(x + y = 36)</u>

 <u>2x   =   40</u>

=> x = 40 / 2 = 20

From (1):

20 - y = 4

=> y = 20 - 4 = 16

The two numbers are 20 and 16.

Write an equation in slope-intercept form and then in standard form for each line described. y-intercept -2; x-intercept 5
Xelga [282]
Hello
the line passes by A ( 0 ; -2)  and B (5 ; 0) equation : y = ax+b
a is a slop : a = (yb - ya)/(xb -xa)
a = (0+2)/(5-0)
a =2/5
y = (2/5)x+b
if x=5 and y= 0
0 = (2/5)(5)+b
b= - 2
the equation is : y = (2/5)x-2
