Which statement correctly explains how Andre could find the solution to the following system of linear equations using
elimination?
(85-9-15
(75-21-12
O Multiply the first equation by -7 and the second equation by 8, and then subtract
O Multiply the first equation by -7 and the second equation by 8, and then add.
O Multiply the first equation by 2 and the second equation by 9, and then add.
O Multiply the first equation by -2 and the second equation by 9, and then subtract.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

the correct answer is $7.38

step-by-step explanation:

what? that isnt a question

step-by-step explanation:

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
