Answer:
y = 2.5x - 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2.5 and c = - 8 , then
y = 2.5x - 8 ← equation of line
4/7 for the 1st one., 8/9 for he 3rd dunno about middle one soz
Easy
leading coefiencet means highest power coefient
degree is the power of the highest exponent
5th degree and leading coefienct is 4
means highest exponet is 5 and the coefienct is 4
means any thing with 4x^5 such that there is no x^n where n>5
4x5 + 3x + 1 is the answer (2nd one)
