General form of the line equation is: y= mx + c
where m is the slope and c is the constant
the slope here is given and equal to 3
so, m= 3
y= 3x +c
to get the constant c, substitute with the point in this equation
y= -2 & x = 1
-2 = 3*1 + c
c = -5
then the equation of the line is y = 3x -5
y = 3x -3 -2
y +2 = 3(x-1)
the answer is (B)
Answer:
Step-by-step explanation:
Given the following coin values ;
A) 1/2 B. 3 cents C. 20 cents D. $2 1/2 E. $5, state it's worth as a percentage of $1
A) $1/2 as a percentage of $1
$1/2 = $0.5
($0.5/ $1) × 100% = 50%
B) 3 cent as a percentage of $1
3 cent = 3/100 = $0.03
($0.03/$1) × 100% = 3%
I'm going to use the substitution method.
If y = - 3/2 - 7, then:
1/2x + 5 = - 3/2x - 7
Combine like terms:
4/2x = - 12. Mutiply both sides by 2/4 to get x = -12 (2/4)
Simplify to get:
x = - 6.
Plug - 6 back in for x in either equation.
Y = 1/2( - 6) + 5 which becomes Y = - 3 + 5.
X = - 6, Y = 2
Answer:
0.6
Step-by-step explanation:
1) 1.4-0.8 (A negative and a positive equals a negative, then you just subtract. On the number line you would start at 1.4 and go back)
