Through: (1,-1), parallel to y = -3
zheka24 [161]

Answer:

The equation of a line parallel to the line and passing through (1, -1) is:

  • y=-3x+2

Step-by-step explanation:

Given the line

y = -3

We know that the slope-intercept form of the line equation is

y=mx+b

where m is the slope and b is the y-intercept

Thus, the slope of the equation y=-3 will be m = -3

We know that the parallel lines have the same slopes.

Thus, the slope of the parallel line will also be -3.

Thus, using the point-slope form to find the line equation is

y-y_1=m\left(x-x_1\right)

substituting the values m = -3 and the point (1, -1)

y-(-1) = -3(x-1)

y+1 = -3x+3

y=-3x+3-1

y=-3x+2

Thus, the equation of a line parallel to line and passing through (1, -1) is:

  • y=-3x+2

Which two triangles are congruent by the HL theorem? The diagrams are not to scale.
SOVA2 [1]
Hello there, and thank you for posting your question here on brainly.

The HL Theorem is when two triangles don't look the same but have the same side lengths.

I'm pretty sure triangles a and c are congruent. 

Hope this helped!! ☺♥

rewona [7]

Answer:

15 days

Step-by-step explanation:

Well, since there are 5 cups of oatmeal, and she eats 1/3 a day, then the equation is: 5 divided by 1/3 then change 1/3 to its reciprocal which is 3. 5 times three is 15 so therefore Stella will finish it in 15 days.

<em>Your welcome.</em>
