Answer:
y=3x-1
Step-by-step explanation:
start at (-1,-4) and go up 6 and over 2, thats your slope or m.
the y intercept is -1
The correct equation should look something like this:
y= -1x - 2
Consider the equation for a line:
y = mx + b,
Where ‘m’ is the slope
Where ‘b’ is the y-intercept.
From there you can plug in your known values for ‘m’ and ‘b’, and get the equation above. If you are still not convinced, I suggest you graph the function and observe its slope and y-intercept.
Hope this helps!
1/6 of a yard is 6 inches. 1/3 of a yard is 12 inches. 5 × 6 = 30. 12 + 30 = 42. 42 ÷ 6 = 7. The student will need to cut 7 pieces of wallpaper.
