b = 9

If the denominator on the right is half of the denominator on the left then the numerator on the right must also be half of the numerator on the left.

The equation in slope intercept form

Solving (3):

$m = -1$

$(x_1,y_1) =(4,-4)$

The equation in slope intercept form is:

$y = m(x - x_1) + y_1$

This gives:

$y = -1(x - 4) -4$

Expand

$y = -x + 4 -4$

$y = -x$

Solving (5):

$m = -3$

$(x_1,y_1) = (1,-5)$

The equation in slope intercept form is:

$y = m(x - x_1) + y_1$

This gives:

$y = -3(x - 1) - 5$

Expand

$y = -3x + 3 - 5$

$y = -3x -2$

Which of the following functions is graphed below?

pishuonlain [190]

Answer: B

The piece wise functions first part says: x is less than it equal to one and has a vertical shift down 4. which would mean the circle is closed and shaded down.

The second part of the function says x is greater than one and has a vertical shift up 3. This would mean it is an open circle and is shaded up.

If y varies directly as x, and y is 18 when x is 5, which expression can be used to find the value of y when x is 11?

Papessa [141]

5/11 = 18/y
5 y = 18 · 11
5 y = 198
y = 198 : 5
y = 39.6
