Question

write an equation of the line with slope 3/7 containing the point (3,8)

Answer 1

y = mx + b
since slope is given that will be the value for m
so now you have
y = (3/7)x + b
now you plug in your values for x and y

8 = (3/7)3 + b
b = 8 - 9/7 = -17/10

so your equation will be
y = (3/7)x - 17/10
