Line Features
1. **Find the features of line A**.
Line A passes through points (1,0) and (0,6).
Gradient (slope) is calculated by: $$m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{6 - 0}{0 - 1} = \frac{6}{-1} = -6$$
The x-intercept is where $y=0$. Given point (1,0), x-intercept is $1$.
The y-intercept is where $x=0$. Given point (0,6), y-intercept is $6$.
2. **Find the features of line B**.
Line B passes through points (0,-2) and (6,4).
Gradient: $$m = \frac{4 - (-2)}{6 - 0} = \frac{6}{6} = 1$$
x-intercept: When $y=0$, find $x$ using the line equation.
Equation in slope-intercept form: $$y = mx + c = 1\cdot x + (-2) = x - 2$$
Set $y=0$: $$0 = x - 2 \Rightarrow x = 2$$
y-intercept is $c = -2$.
3. **Find the intercepts of line given by** $$y - 8x = 24$$.
Rewrite in slope-intercept form: $$y = 8x + 24$$
x-intercept (set $y=0$):
$$0 = 8x + 24 \Rightarrow 8x = -24 \Rightarrow x = -3$$
y-intercept (set $x=0$):
$$y = 8\times0 + 24 = 24$$
**Final Answers:**
- Line A: Gradient = $-6$, x-intercept = $1$, y-intercept = $6$
- Line B: Gradient = $1$, x-intercept = $2$, y-intercept = $-2$
- Line $y - 8x = 24$: x-intercept = $-3$, y-intercept = $24$
