Answer:
11. y = -2x - 4.
12. y = x - 5
Step-by-step explanation:
11. the given points on the line are ((-2, 0) and (0, -4)
The slope of the line
= difference in y values / corresponding difference in x values
= ( - 4 - 0) / 0 - (-2))
= -4 / 2
= -2.
The general form of a straight line is y = mx + c where m = the slope and c = y value of the intercept on the y-axis.
So the equation is:
y = -2x - 4.
12.
The points are (1, -4) and (3, -2).
The slope is (-2 - (-4)) / (3 - 1)
= 2/2
= 1.
So the equation is
y = 1x + c
We find c by plugging in the point (1, -4):
-4 = 1 + c
c = -4 - 1
c = -5.
The equation is y = x - 5.
As the question says that Tory knows for $5 he will get 3.45 euros.
Now for the euro trip he needs to know the rate of conversion or the rate of euros per dollar.
To find the rate of conversion we need to use unitary method.
As we know that at the given rate he gets,
3.45 euros for $5
or the other way around
euros
Now, using the unitary method we get,
euro
Therefore, at the given rate we can see that for each dollar Tory would get 0.69 euro.
Multiply to remove the variable from the denominator.
Step-by-step explanation:
Jacinta is completely right while Tess made a mistake on the 3rd step.
she mistakenly plugged in the y value as X, and plugged in the X value as y.
so Tess is incorrect
