Answer:
see below
Step-by-step explanation:
First find the slope
m= ( y2-y1)/(x2-x1)
= (-5- -7.5)/ ( 2 - -3)
= (-5+7.5) / ( 2+3)
= 2.5 /5
=1/2
Then using the slope intercept equation of a line
y = mx+b where m is the slope and b is the y intercept
y = 1/2x+b
Using a point from above
-5 = 1/2(2) +b
-5 =1+b
Subtract 1 from each side
-6 = b
We have the y intercept
y = 1/2x-6
Tahlia forget to find the y intercept for the equation
Answer:
8
Step-by-step explanation:
put 4 in place for a
4=32
dive both sides by 4 and you will get 8
hope this helps
Answer:
1/3
Step-by-step explanation:
Take any two points: (3,-4) and (0,-5)
y2 - y1 / x2 - x1
-5 - (-4) / 0 - 3
-1 / -3 = 1/3
The answer to your question is 3
