The Vangsgas bill for November was $53. The December bill was 30 more than that, and January's bill was $49 more than December's
bill. They found that the total for the 3 months was $238. Is this
Explain

the right answer is 268

Step-by-step explanation:

Since November was $53 you add 30 more to get Decembers bill you will get it $83 for December. Next you add $49-$83 to your January and that will be 132. You are all through the month so will be $53+$83+132 =268

Step-by-step explanation:

Slope-intercept form implies that we need the slope...so let's do that first. The formula to find the slope being given 2 coordinates is

so filling in:

so the slope is -3. Now we will use that slope in the point-slope form of a line and write the equation.

Point-slope form is

and filling in:

y - 8 = 3(x - 4) (you can choose either point to use for x and y; you'll get the same equation either way...PROMISE!)

y - 8 = 3x - 12 and

y = 3x - 12 + 8 so

y = 3x - 4 and that's the line in slope-intercept form.
