Answer:
The equation i came up with is $55= 7.8x - 47.20
Answer:
30 cm
Step-by-step explanation:
2 * 15: 5 * 15
30:75
Place a point at (0,-5) because that is the y-intercept (the -5 on the vertical line)
Since the slope is negative two which can be re-written as -2/1 (rise/run) you go down two and to the right once or up two and to the left once, it doesn't matter which. Another point can be placed at (1,-7) or (-3,-1), it still doesn't matter which.
Then you can draw a line connecting the two points.
I hope this helps :)
Let me know if you need further explanation
The answer is c. You can plug in the values for x and y and see which ones equal up to 5!
