Which equation represents a side that is perpendicular to side d?

Can you please show the choices so it can be easier ? :)

y=-2x+5

Step-by-step explanation:

m=y2-y1/x2-x1

y^2=5; y1=-1= 5-(-1)

x^2=0; x=3 0-3)

y=mx+b, where m is gradient c= y-intercept.

Taking the point (0,5) this gives

y-5/x-0. = -2 so y=-2x+5 is the answer

step-by-step explanation:

the true ones are a b and d

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
