Answer:
The equation would be Y= -7/2x + 7
Step-by-step explanation:
With the points given (0,7) and (2,0) we find our slope which is: -7/2. We know that our change in the y values is -7 and the change in our x values is +2. Y IS ALWAYS OVER X SO WE GET -7/2.
To find our y intercept you just look at the graph of where there's a point on the y line. For example (0,7) the 7 would be our y intercept.
So we get Y= -7/2x +7
The slope is ALWAYS put next to the variable x.
Hope this helps! :)
(Side Note: You look at the graph from left to right, so our first point would be (0,7)!)
Answer:
y > -5/4
Step-by-step explanation:
12 > -4y + 7
Subtract 7 from both sides:
5 > -4y
Divide both sides by -4 (remember to flip the sign when multiplying or dividing by a negative number):
-5/4 < y
Here's another way to solve it. First, add 4y to both sides.
12 + 4y > 7
Subtract 12 from both sides:
4y > -5
Divide by 4:
y > -5/4
