Find the equation of a line that is parallel to the line x equals negative 1x=−1 and contains the point left parenthesis negativ
sineoko [7]
The equation of the line is given as y-x=-1

A straight line equation is given in the form y=mx+c where m is the gradient and c is the y-interest.

We need to rearrange y-x=-1 to make y the subject. 
y= x-1 ⇒ from here we can read the gradient and the y-intercept. The gradient, m=1 and c=-1.

<span>A line that is parallel to y=x-1 will have the same gradient, m=1 but different y-intercept. One example of equation of a line that is parallel to y=x-1 is y=x+3

PLEASE HELP!! PICTURE INCLUDED!!<br><br> Please explain how to find angle R!!
mafiozo [28]

Answer:

∠ R = 75°

Step-by-step explanation:

you are correct with answers to a, b, c

d

the sum of the 3 angles in Δ QRS = 180° , that is

∠ Q +∠ R + ∠ S = 180° , so

55° + ∠ R + 50° = 180°

∠ R + 105° = 180° ( subtract 105° from both sides )

∠ R = 75°
