The slope (m) is the change in Y over the change in X.

Slope = Y/X

The slope is given as -3/4 , so y would be 3 and X would be 4.

Y = 3

Parallel to y=−3/4x, through (4, -1)
kolbaska11 [484]

Answer:

y=-\frac{3}{4}x+2

Step-by-step explanation:

The slope-intercept form is given by y=mx+c, where m is the slope and c is the y-intercept.

Slope of given line= -\frac{3}{4}

Parallel lines have the same slope. Thus, the slope of the line would also be -\frac{3}{4}.

y=-\frac{3}{4}x +c

The value of c can be found by substituting a pair of coordinates.

When x= 4, y= -1,

-1=-\frac{3}{4} (4)+c

-1= -3 +c

<em>Add 3 to both sides:</em>

c= -1 +3

c= 2

Thus, the equation of the line is \bf{y=-\frac{3}{4}x+2.

Help asap!! There’s a photo
tester [92]

Answer:

C

Step-by-step explanation:

The vertex form for a parabola is a(x-h)^2 + k, where h is the x coordinate of the vertex and k is the y coordinate. a represents the amount that the graph has been "squeezed". Therefore, since the coordinates of the vertex of this parabola are (2,4), and it is "squeezed" by a factor of 2, the correct answer is C. Hope this helps!

Answer:

x^2 -2xy -10y^2

x^2 -9xy +4 y^2

3x^3  +6x^2  -24 x +27

Step-by-step explanation:

3x^2-5xy -6y^2 -( 2x^2 -3xy+4y^2)

= 3x^2- 2x^2 -5xy +3xy-6y^2 -4 Y^2

= x^2 -2xy -10y^2


2x^2−5xy+y^2 -( x^2+4xy−3y^2)

=2 x^2 -x^2 -5xy -4xy +y^2 +3 y^2

=x^2 -9xy +4 y^2


7x^3−16x+18- (4x^3−6x^2+8x−9)

= 7x^3 -4x^3 + 6x^2-16x- 8x +18 +9

=3x^3  +6x^2  -24 x +27
