What is the slope of a line that is perpendicular to the line y = 1?

A. 127 cm^2 b. 144.5 cm^2 c. 172 cm^2 d. 50 cm^2

In which form is the following function written? y = - 2(x – 3)(x + 5)

Sundar used linear combination to solve the system of equations shown. he did so by multiplying the first equation by 5 and the second equation by another number to eliminate the y-terms. what number did sundar multiply the second equation by? 2x+9y=41 3x+5y=36
