You can get the number by dividing 19.2 by 0.40
The number is 19.2/0.40 = 48
Answer: y=4/3x -3
Therefore the slope is 4/3
Step-by-step explanation:
distribute your x to the other side and divide

there are no inflection points, because it never changes concavity, is just a constant and thus for any region over the x-axis, will always be a positive value, and thus is always "concave up".
4/5
2(5x+4)=
distribute the 2
10x+8=
subtract 8 from both sides
10x=8
divide 10 from both sides
x=8/10
simplify by 2
x= 4/5
