check whether the ordered pair is a solution of the equation -y=4x +7.

Answer:
check whether the ordered pair is a solution of the equation -y=4x +7.
Y = 4x - 7 is a line with a slope of 4 and y-intercept of -7.
plug in any X value, for example 1 and you get the following
y = 4(1) - 7
y = -3
(-1,-3) is a point that satisfies the equation y = 4x - 7
