Answer:
y= -2x
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Given that the slope is -2, m= -2.
subst. m= -2 into the equation:
y= -2x +c
To find the value of c, substitute a coordinate.
When x= -4, y=8,
8= -2(-4) +c
8= 8 +c (expand)
c= 8-8 (-8 on both sides)
c=0 (simplify)
Thus, the equation of the line is y= -2x.
<span>If the walkers start at nine and want to join the cyclists at
noon, they will have been walking for 3 hours. At 5 km/h, they would have
walked for 15 km. The cyclists can travel 15 km at 12 km/h in 1.25 hours.
Therefore, the cyclists can start their journey at 10:45 am.</span>

Answer:
x = -7
Step-by-step explanation:
first you collect like terms but since there is an =sign you take +4 over the = to 10 and 6x to 8x it becomes 8x - 6x = -4 - 10 and you solve it becomes 2x = -14 hence answer is x = -7
