Find an equation of the line that satisfies the given conditions. through (−5, −7); perpendicular to the line passing through (−
murzikaleks [220]

Answer:

The equation would be y = 2x + 3

Step-by-step explanation:

In order to solve this, we first need to find the slope of the line between (-2, 5) and (2, 3). In order to do this, we use the slope formula.

m(slope) = (y2 - y1)/(x2 - x1)

m = (3 - 5)/(2 - -2)

m = -2/4

m = -1/2

Now that we have the original line with a slope of -1/2, we can tell a perpendicular line would have a slope of 2. This is because perpendicular lines have opposite and reciprocal slopes. Now we can use that slope and the given point in point-slope form to get the answer. Be sure to solve for y.

y - y1 = m(x - x1)

y + 7 = 2(x + 5)

y + 7 = 2x + 10

y = 2x + 3

Nina saved money in her piggy bank to buy a music player she started by saving 30$ that she received for her birthday and then s
Sedbober [7]

Answer:

No, it does not represent a proportional relationship.

Step-by-step explanation:

The ratios do not reduce to the same value.

40/1 = 40

50/2 = 25

60/3 = 20

We can also tell straight away that this is not a proportional relationship because Nina starts with $30. If the data were graphed, this would mean that the line would not go through the origin. It would start at 30 on the y axis.
