Q. Graphs of linear equations and functions: advancWhich of the following is an equation of the line A graphed in the xy plane that passes through the point (−1,3.5) and is perpendicular to the line B whose equation is x+4.5=0 ?Choose 1 answer:(A) x=−1(B) x=3.5(C) y=3.5(D) y=4.5
Vertical Line Equation: Line B: x+4.5=0 Rewrite in slope-intercept form. x=−4.5 Vertical line, slope is undefined.
Perpendicular Line Slope: Line A is perpendicular to line B. Perpendicular to vertical line is horizontal line. Horizontal line has slope 0.
Horizontal Line Equation: Line A passes through (−1,3.5). Horizontal line through y=3.5. Equation: y=3.5
