4. What is the slope of the equation? y = -x + 3

y = mx + b is  the "slope-intercept" form of the equation of a line ;

We have y = -x + 6 ;

Then, m = - 1 ;

The "point-slope" form of the equation of a straight line is:

y - y1 = m(x - x1) ;  

But, x1 = - 3 and y1 = 8 ;

We have y - 8 = (-1)( x + 3 );

Finally, y - 8 = -( x + 3 );

The right answer is the fourth choice;

y – 3 = (x – 1) ; the equation becames

y = x + 2 ;  

The right answer is the third choice;

Step-by-step explanation:

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
