Step-by-step explanation:
Multiply each number to end up with the answer.
Answer:
2, 4
Step-by-step explanation:
Ok so for this you have to substitute. y=4 so you put a 4 where the y is. This becomes
4 - 3x = -2 We can already rule out (2,2) and (4,2) Why? Because the y is not a 4. So it’s gonna be either (0,4) or (2,4). Now, we have to find x. We have to isolate it. You do this by subtracting 4 from both sides.
4 - 4 - 3x = -2 - 4 Now Simplify
-3x = -6 Why -6? Because you can’t subtract a positive from a negative so it becomes -2 + -4. Since they are both negatives, you just add them together, then put the negative sign.
Now divide -3 from both sides. Which becomes
x = 2
To solve this, you need to know slope-intercept form;
Where mx is the slope and b is the y-intercept form.
Now, looking at the values you have been provided, you can just plug them into the formula.
I cant directly give u the answer but here is some help:
for part a add up and solve the equazions on the whiteboard.
for part b subtract 90 from what you got from part a.
Hope this helps. Sorry i couldnt help more.
