### 1.

GCSE Higher

The equation of the line L1 is $$y = 2 - 5x$$.

The equation of the line L2 is $$3y + 15x + 17 = 0$$.

Show that these two lines are parallel.

### 2.

GCSE Higher

Which of the following lines is parallel to the x-axis?

$$y=-7$$

$$x-y=1$$

$$x=10$$

$$x+y=0$$

$$x=y$$

### 3.

GCSE Higher

Show that line $$5y = 7x - 7$$ is perpendicular to line $$7y = -5x + 55$$.

### 4.

GCSE Higher

The straight line $$L$$ has the equation $$4y = 3x + 5$$.

The point A has coordinates $$(6,7)$$.

Find an equation of the straight line that is perpendicular to L and passes through A.

### 5.

GCSE Higher

Suppose a rhombus ABCD is drawn on a coordinate plane with the point A situated at (4,7). The diagonal BD lies on the line $$y = 2x - 5$$

Find the equation the line that passes through A and C.

### 6.

GCSE Higher

On the grid below, draw the graph of $$y = 1 - 2x$$ for values of $$x$$ from -2 to 2.

### 7.

IB Studies

The vertices of quadrilateral ABCD are A (2, 4), B (-1, 5), C (–3, 4) and D (–2, 2).

(a) Calculate the gradient of line CD.

(b) Show that line AD is perpendicular to line CD.

(c) Find the equation of line CD. Give your answer in the form $$ax+by=c$$ where $$a,b,c\in \mathbf Z$$

Lines AB and CD intersect at point E.

(d) Find the coordinates of E.

(e) Find the distance between A and D.

The distance between D and E is $$\sqrt{20}$$.

(f) Find the area of triangle ADE.
