The equation of line r is y + 1 = -(x +5). line s is parallel to line r and passes through (-10, 3). what is the equation of lines? write the equation in slope-intercept form. write the numbers in the equation as proper fractions, improper fractions, or integers.

The slope intercept form of the line is y = -x - 7

Step-by-step explanation:

In order to find this, we start by noting that the slope will be -1. This is because parallel lines have the same slope. Now that we know this, we can use that and the point in point-slope form to get the equation. Then we can solve for y.

y - y1 = m(x - x1)

y - 3 = -(x - -10)

y - 3 = -(x + 10)

y - 3 = -x - 10

y = -x - 7

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
