Write an equation for the line that passes through (- 3, 5) and is parallel to y = - 6x + 1.
soldier1979 [14.2K]

Answer:

y-5 = -6(x+3) OR y = -6x-13

Step-by-step explanation:

Let's use slope-intercept form to solve this problem.

Slope intercept form is the following:

y-y1 = m(x-x1)

x1 and y1 are given by the point in the problem.

x1 = -3, y1 = 5.

m is given by the equation in the problem. Lines that are parallel have the same slope. Thus,

m = -6.

If we plug these values into the equation for slope intercept form, we get the following:

y-5 = -6(x-(-3)) which becomes y-5 = -6(x+3)

This is an acceptable answer to the problem. However, point-slope form is also a way it can be written.

y-5 = -6x-18

y = -6x-13

The parabola y=x2y=x^2 y=x 2 y, equals, x, squared is scaled vertically by a factor of 110\dfrac{1}{10} 10 1 ​ start fraction, 1
sweet [91]

Question is not well presented

The parabola y=x² is scaled vertically by a factor of 1/10.

What is the equation of the new parabola?

Answer:

The equation of the new parabola is 0.1x²

Step-by-step explanation:

Given

Parabola: y = x²

Scale = 1/10 = 0.1

The interpretation of this question is that; there's a need to scale the graph in ratio 1:10.

I.e; 1 unit on the parabola is being represented by 10 unit on the scale

So, x (on the new parabola) = 1/10 of old x.

So, the new equation of the parabola = 1/10x²

New equation = 0.1x²

Hence, the equation of the new parabola is calculated as 0.1x²
