Step-by-step explanation:
When an equation is in <em>standard form</em> (or almost standard form), I like to put it into <em>intercept form</em> for graphing. Here, it is convenient to divide the equation by 2 to put it in standard form (coefficients mutually prime).
x +3y = -3
Now, it is convenient to divide by the constant on the right (-3) to put the equation into intercept form:
x/(-3) +y/(-1) = 1
The denominators are the x- and y-intercepts, respectively. Plot those, (-3, 0) and (0, -1), and draw the line through them.
To help solve this, we need to use the slope formula.
(y2 - y1) / (x2 - x1). We get these values by picking two points on a line.
For JL, we will pick points (-5, -3) and (-2, -4).
y1 = -4
y2 = -3
x1 = -2
x2 = -5.
Let's plug these into our formula.
(-3) - (-4) / (-5) - (-2) = -1/3
For LN, we will pick points (-2, -4) and (7, -7).
y1 = -7
y2 = -4
x1 = 7
x2 = -2.
Lets plug these values into our equation.
(-4) - (-7) / (-2) - (7) = -1/3
Therefore,
(-3) - (-4) / (-5) - (-2) = (-4) - (-7) / (-2) - (7)
The correct answer is G.
C is the value of x to find it u use the equation 3x=338 and solve
