Answer:
2
Step-by-step explanation:
If we look at the graph this is an increasing graph where y increases with respect to x so in other words we can say that y is directly proportional to x.

and when we remove the proportionality sign we replace it with an equal to sign and a constant. So it becomes ,

now to find the Constant of proportionality which is k we can use any ordered pair(coordinate/point) from the graph,
Lets take ( 2 , 4) where 2 represents the value of x on the x-axis and 4 represents the value of y on the y-axis so now,

so the constant of proportionality is 2
Answer:
A, B, C and D.
Step-by-step explanation:
Opposite sides are congruent (B) as well as the 3 that are marked.
Answer:
25
Step-by-step explanation:
Answer:
A. 3
Step-by-step explanation:
y - 9 = 3(x-2)
y = 3x - 6 + 9
y = 3x + 3
slope is 3x = 3
For you to make an equation a quadratic equation, you need everything to be on one side, so you add one to both sides.
<span>2x^2 + 3x + 0=0 </span>
<span>a=2, b=3, c=0 </span>
<span>b^2-4ac (In the next step just plug in your variables) </span>
<span>3^2 - 4(2)(0) </span>
<span>9 - 8(0) </span>
<span>9 - 0 </span>
<span>Your answer=9</span>
