I need help with my exam, are you willing to help me. I am so lost

1. find the slope and the y-intercept of the line: y=4x-15

the slope is: the y-intercept is (0, )

2. 4x=2y+10

the slope is: the y-intercept is (0, )

3. given fraction f described by f(x)=2x^2-3x+7

f(0)=

f(-5)=

f(3)=

4.equaation of the line

Slope : 7/3,y-intercept :(0,-5)

5. find the equation of the line containing the given pair

(-2,4) and (4,-8)
