y = - 
x - 5
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
here m = -
y = - x + c ← is the partial equation
to find c substitute (- 4, - 3 ) into the partial equation
- 3 = 2 + c ⇒ c = - 3 - 2 = - 5
y = - x - 5 ← in slope-intercept form
Answer: y = 2x + 20
Step-by-step explanation: slope, y2 - y1/x2 - x1
replace it with these numbers 120 - 60/50 - 20=60/30
than,simplified it we get 2/1. so, now we have the slope of our equation
y = 2x + b. but we still have b (or where the y intersects.) now are slope we have to change it to 1/2 because we are going backwards. So multiply 60 by .5, Thus will give us 30
Now we have y = 2x + 30, But that's not one of your answer,
So y = 2x + 20 cant be -20 because this is a positive y intersect and We know it is a slope of 2.
Therefore the answer is : y = 2x + 20
ALSO I got it correct on the test!!
Your answer is going to be A, B, and D :)
Answer:
its A=4,20, B=8,40
Step-by-step explanation:
you are supposed to do the Y first then the X
