Solve this system of equations by graphing. First graph the equations, and then type the solution. 2x+5y=-10 and y=-3/5x-1

From the graph, it is clear that both lines intersect at x=5 and y=-4

Thus, the point of intersection is (x, y) = (5, -4)

(x, y) = (5, -4)

Please check the graph.

Step-by-step explanation:

The solution graph is attached below.

From the attached solution graph,

From the graph, it is clear that both lines intersect at x=5 and y=-4

Thus, the point of intersection is (x, y) = (5, -4)

Therefore, the point of intersection is the solution to the system of equations.

Hence, the solution is: (x, y) = (5, -4)

Please check the graph.

LET US SOLVE TO CHECK

solve for y

Divide both sides by -5

Thus, the solution is:

9

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
