Front

What are lines that are always the same distance apart and will never intersect/ join.

Back

Parallel lines

Front

lines intersect at a 90-degree angle, forming a right angle.

Back

Perpendicular lines

Front

determine whether this equation is parallel or perpendicular y=3x-4 p(6,4)

Back

-14=c

(y=3x-14)

Front

determine whither this equation is parallel or perpendicular (2y+4x=5) (y-1/2x=4)

Back

      2           2

Front

What is the formula for gradient?

Back

m= y2​−y1

      x2-x1

Front

What is the formula for y-intercept?

Back

y=mx+c

Front

determine the midpoint, gradient and y-intercept using the given Points A(9, 8), B(7, 10)

Back

Midpoint= (9+7 , 8+10) = (16, 18 ) = (8 , 9)

     2      2           2   2

Gradient: (10-8 )= 2 =-1

             7-9   -2

Y-intercept: y=mx+c

7=-1(10)+c

7+10=c

17=c
