Slope that goes through points -15,70 and 5,10

The slope is ( 10 - 70 ) / ( 5 + 15 ) = ( - 60 ) / 20 = - 3;

Step-by-step explanation:

Step-by-step explanation:

You have to use this formula: Y2 - Y1

                                                 X2 - X1

(-15,70) ]& (5,10):

Y2 - Y1

X2 - X1

10 - 70

5 - - 15

-60

20

Simplified because both -60 & 20 can be divided by 10: -6

                                                                                              2

Simplified again because -6 & 2 can be divided by 2: -3

                                                                                          1

IF the 1 is NOT needed, then it's just -3!!! :)

Really really sorry if I'm incorrect!!!

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
