If signs are different you subtract. So 2.5- -1.25 equals 1.25 and keep the sign of the biggest number
The answer is the first one, 35000.
B. 2
if any other number was in there i dont think it would work because its neg
75/15=5
3*5=15
y would equal 15
Hope this helps :)
Answer:
y= -2x+9
Step-by-step explanation:
The equation will be written this way :
y= m*x+c
- m is the slope
- c is a constant
- m =( f(4)-f(2))/(4-2)=(1-5)/2= -4/2 = -2
- y = -2x+c
- replace x and y by the coordinates of a point to get c
- 1= -2*4+c
- c = 9
y = -2x+9
