Answer:0,10, 10,0.

Step-by-step explanation:

The equation is in point-slope form, y − y1 = m(x − x1), where the slope, m, is -1, and the line goes through the point (4,6).

Use the slope to find a second point on the line. So, from the point (4,6), go down 1 unit and to the right 1 unit. Therefore, the line also goes through the point (3,5).

This is the graph showing a line that goes through (4,6) and (3,5).

Answer:

All but the second one

Step-by-step explanation:

The rule of a function is that you can't have the same x values in an expression. You can have multiple y values but not multiple x values.

You have 8 times as many dimes as nickels. You have 18 dimes

Answer:

$1.70

Step-by-step explanation:

Let the number of nickels be $x$ .

Thus, by the problem statement, the number of dimes is [/tex] 8 \cdot x = 8x. [/tex]

Therefore, there are $8x + x = 9$ coins in total. To find what $x$ is, we need to solve the equation $9x = 18.$ This can be done by dividing both sides by $9$ which gives $x=2$ . Plugging these values in tells us that there are $2$ nickels and $16$ dimes. (Test it out!) Thus, the nickels are worth $2 \cdot 5 = 10$ cents and the dimes are worth $16 \cdot 10 = 160$ cents, so in all, you have $10 + 160 = 170$ cents which is $1.70.
