The required equation of the line passing the coordinates will be y = 3/4x - 1/4
<h3 /><h3>Equation of a line</h3>
The standard equation of a line is expressed as y= mx + b
where
m is the slope
b is the y-intercept
Given the coordinate points on a line (3, 2) and (-1, -1)
Slope = -1-2/-1-3
Slope = 3/4
Determine the y-intercept
2 = 3/4(3) + b
2 = 9/4 + b
b = 2 - 9/4
b = -1/4
The required equation of the line passing the coordinates will be y = 3/4x - 1/4

Answer:
Tayler has 35 SHKITTLES IN ALL
Step-by-step explanation:
Since Tayler has 20 red Skittles, and the ratio of blue skittles to red skittles is 3 to 4, that means that Tayler has 3/4 as many blue skittles as she does red skittles. 3/4 of 20 is 15
20 + 15 = 35
Thus, Tayler has 35 skittles
SHKITTLES lol
X is a number so when u plus a letter that's still a number
Answer:
Either 43 or 88
Step-by-step explanation:
45/3 = 15 (one witch)
21/3 = 7 (one broom)
12/3 = 4 (one spoon)
PEMDAS:
Equation: 15 + 7 x 4
if there are parenthesis and the equation looks like:
(15 + 7) x 4
the <u>answer is 88</u>.
if there is NOT parenthesis and the equation looks like:
15 + 7 x 4
the <u>answer is 43</u>.
We have that
<span>sin x=2/9
we know that
sin</span>² x+cos² x=1---------> cos² x=1-sin² x-----> cos² x=1-(2/9)²
cos² x=1-(4/81)------> (81-4)/81-----> 77/81
cos x=√(77/81)
Sin 2x = 2 sin x cos x-------> 2*(2/9)*(√(77/81))----> (4/81)*√77---> 0.43
Sin 2x=0.43
so
cos² 2x=1-sin² 2x---------> 1-[0.43]²-----> 1-[0.1878]----> 0.81
cos² 2x=0.81-----------> cos 2x=0.9
tan 2x=sin 2x/cos 2x--------> tan 2x=0.43/0.9---------> tan 2x=0.48
the answers are
sin 2x=0.43
cos 2x=0.9
tan 2x=0.48
