Example: y = 2x + 1 is a linear equation: The graph of y = 2x+1 is a straight line. When x increases, y increases twice as fast, so we need 2x. When x is 0, y is already 1.
answer is equal to 82 coz x =9 and y=1
Answer:
2 seconds

You could plot it on Desmos.
Answer:
B) Y = 5x - 10
Step-by-step explanation:
m = y2-y1 / x2-x1
Hope this helps. Pls give brainliest.
Answer:
x = 7; y = 77
Step-by-step explanation:
y = 9x + 14
y = 4x + 49
Since both equations are solved for y, set the two right sides equal and solve for x.
9x + 14 = 4x + 49
5x = 35
x = 7
Sow substitute 7 for x in the first equation and solve for y.
y = 9x + 14
y = 9(7) + 14
y = 63 + 14
y = 77
Answer: x = 7; y = 77
