The diagram shows the graph of y = 2x + c, where c is a constant find the value of k.

Step-by-step explanation:

The equation is a linear equation. By definition, the independent term on this equation (that is, the number that is not being multiplied by ) is the y-intercept, which is a fancy way of saying "the point where the line crosses the y-axis".

By looking at the equation, we know that our y-intercept is c. By looking at the graph, we can see that the y-intercept is -3. Therefore, and we get the complete version of our linear equation:

Now, looking at the graph we can see that the point lies on the line of the equation, which means that the point is a solution to our equation. All we have to do is replace and by the values of the given point (which are and , respectively), and then solve for :

And we are done!

step-by-step explanation:

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
