Question

Write an equation is slope-intercept form for the line parallel to y=7x+9 that passes through (4,10)

Answer 1

Since they are parallel, the co-efficient of x will be the same. So m=7.
Y=Mx+c. So if we substitute the values with the coordinates, we get 10= (7*4) +c . Therefore c= -18.
So the final answer is:

Y=7x - 18
