Answer:
y= -4x + 3
Step-by-step explanation:
Because the slope is -4/1 which is the same as 4 and 3 is the y-intercept.
Here's the work;
We can just use the first two coordinates which are (0,3) and (1,-1) to get from the x-value 0 to 1 we add 1. and to get from the y-value 3 to -1 we subtract 4. Therefore the slope is -4 and the y- intercept (when x is zero) is 3. Pop that into slope intercept form to get y=-4x +3
Hope that helps and have a great day!
2/10 and 2/100 would be the fractions and 0.20 and 0.02 would be the decimals
The axis of symmetry would be (5, -27). To find the axis you can use two equations but for this question I used -b/2a. In the equation, the a is 1 and the b is -10. So, you would substitute it in and get 10/2 which would give you x=5. Then, you would substitute it into the equation. Like this —> y=(5)^2-10(5)-2. You would end up with y=25-50-2. This would give you a y of -27 leaving you with the answer (5,-27).
