Calculate the slope between the points (2,0) and (6, 7)

slope = 1.75

Step-by-step explanation:

slope = Y2-Y1/X2-X1

= 7/4

= 1.75

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
