Answer:

-2x+6.

Step-by-step explanation:

1) if A(1;4), B(2;2), then the required equation is:

2) $\frac{x-X_A}{X_B-X_A} =\frac{y-Y_A}{Y_B-Y_A}; \ => \ \frac{x-1}{2-1}=\frac{y-4}{2-4}; \ => \ \frac{x-1}{1}=\frac{y-4}{-2};$

3) if to re-write this equation as slop-interception form, then:

y= -2x+6.

Find the coordinates of the point on the curve y = 2x² - x - 1 at which the gradient is 7

madreJ [45]

Answer:

See below

Step-by-step explanation:

The derivative of the function is the slope

2x^2 - x -1 take derivative ( f ' )

4x -1 equate to 7

7 = 4x -1

x = 2 sub into the original equation to find y = 5

The figure shown is made up of a square and a triangle. Express the area of the figure in terms of y.

Doss [256]

Answer:

$y^2+2y$

Step-by-step explanation:

The area of a square can be found by $s^2$ and the area of a triangle can be found by $\frac{1}{2}b*h$ .

The area of the square with side length y is $y^2$ .

The area of the triangle with the base 4 and height y is $\frac{1}{2}4*y = 2y$

Adding the areas together gives $y^2+2y$

Write the equation of a line parallel to the line: y=-x-4 that goes through the point (-9,8)

Ymorist [56]

Answer:

y=-x-1 or, y-8=-1(x+9)

Step-by-step explanation:

Parallel lines have the same slope. in your current equation you have a slope of -1. We can use this slope and your set of points in the point slope formula.

y-y1=m(x-x1)

(-9, 8)

x1 y1 m=-1

y-8=-1(x+9)

y-8=-1x-9

+8 +8

y=-x-1
