Answer:
4
Step-by-step explanation:
slope,m=0 and y-intercept (0,4) means this is a horizontal line that crosses the y-axis at 4. so, y=mx+b becomes y=b or y=4 which is the equation of given line.
Heres a tip, multiply the numbers without any decimals then when done, add how many decimal places there are in total.
Ex:16.28 x 4 = 65.12
1625 x 4 = 6512
Exact form: x= plus or minus the square root of 11 plus 2
Decimal form:
X= 5.32 X= -1.32
If that’s not what your looking for then the answer is: y= 4(x-2)^2 -9
