Answer:
y = -1/2 x - 3 1/2
Step-by-step explanation:
points (1, -4) (3,-5)
slope = (y2-y1)/ (x2-x1)
slope = (-5--4)/(3-1)
= (-5+4) /2
=-1/2
point slope form of a line
y-y1 = m(x-x1)
y--4 = -1/2 (x-1)
y+4 = -1/2 (x-1)
if we want slope intercept form
distribute
y+4 = -1/2 x + 1/2
subtract 4 from each side
y+4-4 = -1/2 x + 1/2 -4
y = -1/2 x - 3 1/2
Answer: 4 units
Step-by-step explanation:
Answer:
70
Step-by-step explanation:
Your best bet is to make a table of the x and y values.
Then plug -2, -1, 0, 1, and 2 in for x, into the equation to get the y values. That's how you get your points.
6*10^10 would equal 60000000000 and 3*10^6 would equal 3000000
