If the slope is -3 and (1, 2) is a point on the line, what is the equation of the line?

Answers

Answer: y=-3x+5

Step-by-step explanation:

First write in point slope form, y-y1=m(x-x1) which is y-2=-3(x-1). Then distribute the -3 and add the negative 2 to the other side to solve for y.

The point-slope form of the equation of the line that crosses point (-2,5) and is parallel to
y=-4x-1, is

Answer:

The slope will be y=-4x-3

Question 14 options:

1)

6 × 3 × 3

2)

3 × 6 × 6

3)

9 × 6 × 6

4)

6 × 9 × 9

Answers

Answer:

1) 6 * 3 * 3

Step-by-step explanation:

Assuming the box is a cube, the surface area would be 6 times one side's area (since in a cube each side is a square) or A=6s^2 where s is a side length of the cube. This means that the surface area is 6*3*3=6*9=54 in^2

I need help , I really don’t understand it .

Answers

Answer:

slope intercept form is the form of y=mx+b, where the slope is m and the y intercept is b.

what you have to do is to solve the equations for y.

1) 2x+2y = 10

  2y = 10 -2x

    y = -x +5

2) 12+4y = -4x

    4y = -4x-12

       y = -x -3

lines are parallel when they have same slope and different y-intercepts. m1=m2 and b1 ≠ b2

lines are perpendicular when the multiplication of their slope gives -1

m1 x m2 = -1

here the slopes are same and y-intercepts are different so lines are parallel.
