Hello, can someone help me with these ones pls? I need it ASAP Find the slope of the line in each figure. If the slope of the li
sp2606 [1]

Answer:

slope: -3

equation: y = -3x

Step-by-step explanation:

the slope is "the amount of change in the y direction when you take one step to the right".

In the first graph you can see that (0,0) and (1,-3) are on the graph. So when you step from x=0 to x=1, the graph moves 3 units down. Hence the slope is -3. The minus sign means down.

Sometimes it is difficult to see the change in the y direction when only taking 1 step to the right. That's no problem, if you take e.g., 4 steps to the right, you have to divide the y change that you found by 4.

Written in a formula it is dy/dx, a.k.a: the y change divided by the x change.

So that takes care of the slope.

In a general formula for a line y = ax + b, the slope is the letter a.

b is used to move the graph up and down. The first graph moves through (0,0) so no b needed, hence the equation y = -3x.

If b would be, say, 5, the graph would be lifted up by 5. In fact, the point (0,b) will be the point where the graph crosses the y-axis. So you find b by finding the intersection with the y axis. x must be 0 at this point.

With this approach you can solve all assignments easily.

astra-53 [7]

Answer:

Multiply 9 by 6

Step-by-step explanation:

7:9 is the ratio

We multiply the first term by 6.

What we do to one side, we do to the other

7*6=42

9*6 = 54

That way we keep the ratio in the same proportion

42:54
