In Y=-3x+5 the slope is: -3 and the Y intercept is 5.
Explanation:
The equation without any actual inputs is: Y=mX+B. m refers to the slope. B is the Y intercept. So when looking at the equation with information inputted. You would follow the same structure. Slope will be with the X and Y intercept will be added after.
X/49 = 21/x
x^2 = 21(49) = 1029
x = √1029 = 32.1
x = 32.1
0.8 is greater because 3/4 equals .75
I think that it is attempt. If i am wrong, sorry.
