change in y/change in x

y2-y1/x2-x1

-1--5/0-2

-1+5/-2

4/-2

-2

slope is -2

now take one ordered pair and plug it into the equation (for this example i will use the SECOND ordered pair

y = -2x +b

-1 = -2(0)+b

-1 = b

Write the equation of the line with slope 8 and passes through the point ( - 9, - 7)
AleksAgata [21]

Answer:

<h2>y = 9x + 65</h2>

Step-by-step explanation:

To find the equation of the line given the slope and a point we use the formula

y -  y_{1} = m(x - x_{1})

where

m is the slope

( x1 , y1) is the point

From the question the slope is 8 and the point is ( - 9 , - 7)

Substitute the values into the above formula and solve for the equation

We have

y  + 7 = 8(x + 9) \\ y + 7 = 9x + 72 \\ y = 9x + 72 - 7

We have the final answer as

<h3>y = 9x + 65</h3>

Hope this helps you

Anni [7]
3x-4y=10
-20-x+2y=10 then -30+2y=x now plug this in the other equation:
3(-30+2y)-4y=10
-90+6y-4y=10
2y=100
y=50
