The answer would be m = -1/7 or -0.143
Since we are given the value of b (-3) and a coordinate (7, -4), All you have to do is plug the x-coordinate into x and the y-coordinate into y; simplifying the equation to (-4 = m*7-3). Using simple algebra, find m by adding 3 to -4. Finally, divide that by 7 to get your final answer, (-1/7).
Y=12x-1y=1\4 y=12x 1y =1\4 x-4 y=12x-1y 12x-1y=1\4 y=12x1y1\4 y=12x-1y=\x-4y=1x-y 12x-y 4{12x-y}=4{-/x/-4} y=12x -y 4 12x-4y=4x\x -y=12x-x-y
Answer:
x=12
Step-by-step explanation:
5(x-6)=2(x+3)
5x-30=2x+6
5x=2x+36
3x=36
x=12
Answer:
see explanation
Step-by-step explanation:
The slope m of the line = tan45° = 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 1 , then
y = x + c
To find c substitute (2, 1 ) into the equation
1 = 2 + c ⇒ c = 1 - 2 = - 1
y = x - 1 ← equation of line
When x = 0 then y = 0 - 1 = - 1
The line passes through (0, - 1 )
Note the equal sign. What you do to one side, you do to the other.
Also, remember to do the opposite of PEMDAS.
First, subtract 6 from both sides
-2x + 6 (-6) = -20 (-6)
-2x = -26
Next, isolate the x. Divide -2 from both sides
(-2x)/-2 = (-26)/-2
x = -26/-2
x = 13
13, or (B) is your answer
