Answer:

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.
Parallel lines have the same gradient. Hence the gradient of line r is
.
Susbt. m=
,

To find c, substitute a coordinate.
When x=3, y= -9,

-9= 1 +c
c= -9-1
c= -10
Thus the equation of line r is
.
Answer:
11/10
Step-by-step explanation:
4\5 + 3/10
U need to make the denominator the same. 10 is a multiple of 5. to get 10 u times by 2
so 4\5 times by 2 =8/10 whatever you do to the denominator you do top. now you add the numerators 8+3= 11 so ur answer is 11/10
