What is the slope of the line that<br> passes through these two points?<br> (-1, 4)<br> (2, 2)

Dimas [21]

Answer:

-2/3x

Step-by-step explanation:

1.) use the slope equation (y2-y1)/(x2-x1)

2.) substitute the points into the equation (2-4)/(2--1)

3.) solve the equation (2-4= -2) / (2--1=3)

4.) the slope is -2/3

Answer:

5. $y=\frac{1}{3}x-3$

6. $y=\frac{1}{4}x+4$

7. $y=-5$

8. $y=x+5$

9. $y=\frac{-1}{2}x+6$

10. $y=-4x+2$

Step-by-step explanation:

5. Slope = $\frac{-1-0}{6-9}$ = $\frac{-1}{-3}$ = $\frac{1}{3}$

$y=\frac{1}{3} x+b\\0=\frac{1}{3}(9)+b\\0=3+b\\b=-3$

6. Slope => $\frac{2-6}{-8-8} = \frac{-4}{-16} = \frac{1}{4}$

$y = \frac{1}{4} x+b$

$6=\frac{1}{4}(8)+b\\6=2+b\\b=4$

7. Slope => $\frac{-5-(-5)}{-4-7}=\frac{0}{-11} =0$

$y=-5$

8. Slope => $\frac{4-7}{-1-2} = \frac{-3}{-3} = 1$

$y=x+b\\7=2+b\\b=5$

9. Slope => $\frac{10-4}{-8-4} = \frac{6}{-12}= \frac{-1}{2}$

$y=\frac{-1}{2}x+b\\4= \frac{-1}{2}(4)+b\\4=-2+b\\b=6$

10. Slope => $\frac{14-2}{-3-0} =\frac{12}{-3} =-4$

$y=-4x+b\\2=-4(0)+b\\b=2$

Answer:

first

area of rectangle = l*b

= (3x-y+4) ( X+7)

= 3x²-xy + 4x+21x-7y+28

= 3x²-xy +25x-7y +28

Area of square = l²

= (x-2)²= x²- 4x +4

area of shaded region=( 3x²-xy +25x-7y +28) -(x²- 4x +4)

=2x²-xy +29x-7y+24
