Answer:
Step-by-step explanation:
One of the easier approaches to graphing a linear equation such as this one is to solve it for y, which gives us both the slope of the line and the y-intercept.
x-3y=-6 → -3y = -x - 6, or 3y = x + 6.
Dividing both sides by 3, we get y = (1/3)x + 2.
So the slope of this line is 1/3 and the y-intercept is 2.
Plot a dot at (0, 2). This is the y-intercept. Now move your pencil point from that dot 3 spaces to the right and then 1 space up. Draw a line thru these two dots. End.
Alternatively, you could use the intercept method. We have already found that the y-intercept is (0, 2). To find the x-intercept, let y = 0. Then x = -6, and the x-intercept is (-6, 0).
Plot both (0, 2) and (-6, 0) and draw a line thru these points. Same graph.
Answer:
2.66 or 2 2/3

Answer:
a = - 27
Step-by-step explanation:
- 
a - 6 = 12 ( add 6 to both sides )
- a = 18 ( multiply both sides by 3 to clear the fraction )
- 2a = 54 ( divide both sides by - 2 )
a = - 27
I multiplied 17.5 times 2.48 and got 43.4
