Are the lines described by the equations y=x+2 and x+y=6 intersecting, coinciding, or parallel? Explain
Novosadov [1.4K]
<span>y = slope*x + y-intercept;
</span>We can rewrite our equation in a shorter form : y = mx + b;
y = x + 2 ; m1 = 2 and b1 = 2;
y = -x + 6; m2 = -1 and b2 = 6;
<span>Set the two equations for y equal to each other:
</span>x + 2 = -x + 6 ;
<span>Solve for x. This will be the x-coordinate for the point of intersection:
</span>2x = 4;
x = 2;
<span>Use this x-coordinate and plug it into either of the original equations for the lines and solve for y. This will be the y-coordinate of the point of intersection:
</span>y = 2 + 2 ;
y = 4;
<span>The point of intersection for these two lines is (2 , 4).</span>

Which proportion is equivalent to a/b = c/d
PilotLPTM [1.2K]
The proportion equal to a/b = c/d is A.) A/C = B/D

We will know if a proportion is equivalent when its cross products are equal.

a/b = c/d where ad = bc

since ad = bc, a/c = b/d
