Question

Write the standard form of the equation of the line that is parallel to the given line,
y = −2x + 6, and passes through 0,−2

Answer 1

you need to find the slope. In y = mx + b form, the m position stands for the slope. So what is your slope in y = -2x + 6 ?

Answer 2

so what's the answer sir? :)

Answer 3

Since you are looking for a parallel line, the slope will be the same. you will then use : y - y1 = m(x - x1)
slope(m) = -2
(0,-2) x1 = 0 and y1 = -2

now lets sub.

y - (-2) = -2(x - 0)
y + 2 = -2x + 0
y = -2x + 0 - 2
y = -2x - 2

standard form...
y = -2x - 2
2x + y = -2 (standard form)

Answer 4

any questions ?

Answer 5

Done it perfectly sir, Thanks a lot :)

Answer 6

yes, i have many questions sir :)

Answer 7

ask away ?

Answer 8

Write the equation of the line, in slope-intercept form, that passes through the point
−5,5
Ê
Ë
ˆ
¯
and has slope −3.

Answer 9

slope(m) = -3
(-5,5) x1 = -5 and y1 = 5

y - y1 = m(x - x1)
y - 5 = -3(x - (-5)
y - 5 = -3(x + 5)
y - 5 = -3x - 15
y = -3x - 15 + 5
y = -3x - 10 <-- slope intercept form

Answer 12

5. Graph the linear system and determine how many solutions it has: no solution, exactly one solution or
infinitely many solutions. (3 points)
a.
x + y = 2
3x − 2y = 6
b.
3x + y = 1
2y = 2 − 6x
c.
4x − 2y = 8
2x − y = 7

Answer 13

(a) x + y = 2 --> x = -y + 2
now sub -y + 2 in for x in the other equation
3x - 2y = 6
3(-y + 2) - 2y = 6
-3y + 6 - 2y = 6
-5y = 6 - 6
-5y = 0
y = 0
now sub 0 in for y in the first equation
x + y = 2
x + 0 = 2
x = 2
check...
3x - 2y = 6
3(2) - 2(0) = 6
6 - 0 = 6
6 = 6 (correct)

x = 2 and y = 0 (One solution)

(b) 3x + y = 1
y = -3x + 1
now sub -3x + 1 in for y in the other equation
2y = 2 - 6x
2(-3x + 1) = 2 - 6x
-6x + 2 = 2 - 6x
-6x + 6x = 2 - 2
0 = 0

INFINITELY MANY SOLUTIONS

(c) 2x - y = 7
2x - 7 = y
now sub 2x - 7 in for y in the other equation
4x - 2y = 8
4x - 2(2x - 7) = 8
4x - 4x + 14 = 8
0 = -14 + 8
0 = - 6

NO SOLUTION
