Find an equation of a line through (0, -7) and parallel to the line y=1/2x+5.
marysya [2.9K]

Answer:

The answer to your question is y = 1/2x - 7

Step-by-step explanation:

Data

Point = (0, -7)

line = y = 1/2x + 5

Parallel line have the same slope.

Slope of the first line = 1/2

Slope of the new line = 1/2

Equation of the line

                y - y1 = m(x - x1)

Substitution

                 y + 7 = 1/2(x + 0)

Simplification

                 y + 7 = 1/2x

result

                 y = 1/2x - 7

Point A lies on the circle and has an x-coordinate of 1.
stellarik [79]

Answer:

\sqrt{(0-y)^{2}+(0-1)^{2}}=2

Step-by-step explanation:

we know that

In the circle of the figure the radius is equal to 2 units

The distance from the center of the circle (origin) to the point A must be same at the radius

so

Applying the formula's distance between two points

point A( 1,y) and point (0,0)

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

substitute the values

2=\sqrt{(0-y)^{2}+(0-1)^{2}}

rewrite

\sqrt{(0-y)^{2}+(0-1)^{2}}=2
