Consider the line y = -7x+6.
find the equation of the line that is parallel to this line and passes through the point (
5
5
)
find the equation of the line that is perpendicular to this line and passes through the point (5,-5).

For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis

We have the following equation:

With slope

By definition, if two lines are parallel then their slopes are equal. Thus, a parallel line will be of the form:

We replace the point (5,5) through which the line passes and find "b":

Finally, the equation is:

On the other hand, if two lines are perpendicular then the product of their slopes is -1. Thus, the slope of a perpendicular line will be:

Thus, the equation is of the form:

We substitute the point (5, -5) through which the line passes and find "b":

Finally, the equation is:

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
