When graphing the equation y=-3x+2, a student plotted the y-intercept at 2, then moved down three units and to the left 2 units because the slope is negative, so both rise and run are negative. Find this error and correct it.

Answer:
The error is founded in the slope, specifically in the run.
When seen a negative slope, that only applies to the rise but <u>not</u> the run.
Instead, the student should run 1 (not 2) units to the <u>right</u>.
The slope had not mentioned any 2 in the run.
So it would sound like down 3, over 1, starting from 2.
The y intercept at 2 is correct. This is the location (0,2)
The slope is -3 or -3/1, meaning that we move down 3 and to the right 1 unit. Doing so has us go from (0,2) to (1,-1). Plot these two points together on the same xy grid and draw a straight line through the two points.

Answer:
222- 50+1=0? 225 - 50 = 175 175+1 = 176 176+0 = 176
Answer:
No mistake
Step-by-step explanation:
2x + y = 5
x - 2y = 10
y = 5 - 2x
x - 2(5 - 2x) = 10
x - 10 + 4x = 10
5x - 10 = 10
5x = 20
x = 4
2(4) + y = 5
y = -3
She made no mistake
You can check by plugging in x = 4 and y = -3 into the original equations . They fit exactly.
Answer:
x= 6
Step-by-step explanation:
3(x + 4) = 2x + 4x - 6
3x + 12 = 2x + 4x - 6
3x + 12 = 6x - 6
-3x = -18
x= 6

<span>the answer is 59.25 – 8.67 = </span>50.58
15:24 to the lowest term is 5:8. This is because you divide each number by the same number. You will divided 15 and 24 by 3 to get 5:8.
