Answer:
Then the desired equation is y = -2x - 6.
Step-by-step explanation:
As we move from point (-3, 0) to point (0, -6), x increases by 3 and y decreases by 6. Thus, the slope of the line segment connecting these two points is m = rise / run = -6/3 = -2.
Now use the slope-intercept equation of a straight line to determine the y-intercept of this line:
y = mx + b becomes 0 = -2(-3) + b, so that b = -6.
Then the desired equation is y = -2x - 6.
Check: Does (0, -6) satisfy y = -2x - 6? Is -6 = -2(0) - 6 true? YES
Answer:
x = 0

Answer:
Welder A has a better deal because for each hour welder A would charger $75 while welder B would charge $80
Welder A:
300/4 = $75
Welder B:
240/3 = $80
6 2/3 divided by 2/3 is 20/3 * 3/2 = 60/6 = 10 hours
I used the trick that dividing two fractions is the same as multiplying by the inverse. (ie., divide by 2/3 is like multiplying with 3/2)
