Step-by-step explanation:
let (-2,4)=(x1,y1)
given eqn: y=4x+11
comparing with y=mx+c
slope (m)=4
now using point and slope form,
(y-y1)=m (x-x1)
(y-4)=4 (x+2)
y-4=4x+8
4x-y+12=0 is required eqn.
This is the overall final answer in fraction and decimal form.

Step-by-step explanation:
Given data
Distance = 24.6km
in meters= 24.6*1000= 24600m
time= 30 minutes
in seconds= 30*60= 1800
int hours= 0.5 hour
speed of the particle in
(i) km/h= 24.6/0.5= 49.2 km/h
(ii) m/s.= 24600/ 1800= 13.66 m/s
The equation of a line given the slope and y-intercept is given as;
m(x-x₁) = (y-y₁)
∴equation of line with m = 2 and y-intercept = (0,3) =
2(x - 0) = (y - 3)
= 2x - 0 = y - 3
making y the subject obtains y = 2x + 3.
so, equation of the line: y = 2x + 3.
