Answer:

Question 9: The second answer choice:  m = - 3 ; b = - 4

Question 10: the last answer choice:  m = -1/2 ; b = -3

Step-by-step explanation:

Question 9 )

We want to find the slope and y intercept of the equation y = -3x - 4

The equation appears to be in slope intercept for, y = mx + b

Where m = slope and b = y intercept

In the equation , -3 takes the spot of "m" meaning the the slope is -3, and -4 takes the spot of b meaning that they intercept is -4.

So m = -3 and b = -4

Question 10 )

Like question 10 we want to find the slope and y intercept of an equation

y = -1/2x - 3

Once again the equation appears to be in slope intercept form , y = mx + b

where m = slope and b = y intercept

In the equation -1/2 takes the spot of m, meaning that the slope is -1/2 and -3 takes the spot of b meaning that the y intercept is -3

So m = -1/2 and b = -3

Remember from now on ;

1 ) The coefficient of x in this form of equations * y = ax + b * is the slope of the function which is a .

2 ) Where ever you wanna find the y-intercept you must to put 0 instead of x and find the y's value ;

Or on the other hand we can say the b or the lonely number in this form of equations * y = ax + b * , is the y-intercept of the function.

Q 9 )

[tex]slope = m = - 3[/tex]

And

[tex]y = - 3x - 4[/tex]

[tex]y = - 3 \times (0) - 4[/tex]

[tex]y = 0 - 4[/tex]

[tex]y = - 4[/tex]

Thus the second option is the correct one.

Q 10 )

[tex]slope = m = - \frac{1}{2} \\ [/tex]

And

[tex]y = - \frac{1}{2} \times (0) - 3 \\ [/tex]

[tex]y = 0 - 3[/tex]

[tex]y = - 3[/tex]

Thus the last option is the correct one.
