Answer:
The steps are are explained below.
Step-by-step explanation:
Given:
The equation of the line is given as:
The above equation is in point-slope form .
Therefore, on comparing, we get
So, the slope is one-third and point is (-2,4).
Now, following are steps for plotting the graph:
i. Plot the point (-2,4).
ii. Since the slope is one-third, it means we need to move 3 units to right from the point (-2,4) and then 1 unit up. So, after translating 3 units right and 1 unit up we mark the second point which is .
iii. Draw a line passing through the points (-2,4) and (1,5) to get the graph of the line
Thus, the graph is drawn below.
Answer:
y = 5
Step-by-step explanation:
22.5(10-y)+27.5y=250
Combind like terms,
Subtract 225 from both equations to isolate the variable.
Divide both sides by 5 to isolate the variable and solve it.
