If you were to use the substitution method to solve the following system, choose the new system of equations that would result if x was isolated in the second equation. 3x – 5y + z = 12 x + 6y – z = –4 2x – 5y – 2z = –8

What is the equation of the line that passes through the point (2, 3) and is perpendicular to the line y = –x – 3?

OpenStudy (anonymous):

the slope of y=-1x-3 is -1 ok ? for a line perpendicular to it u should chose ur slope=-1(ex slope ) here slope = -1(-1)=1 the formula is y=mx+a substitute the slope with m and by plugging the point in the equation find a
