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
the equation is
<h2>
y = -2x - 1</h2>
Answer:
x= -6
Step-by-step explanation:
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

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

We have the final answer as
<h3>y = 9x + 65</h3>
Hope this helps you
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
The middle right is 145-90, so 55°. I'm not sure about the others
