write the equation of the line with slope 2 that passes through the point (1,5)

recall slopepoint form:
y  y1 = m(x  x1)
where
m = slope
(x1, y1) = point on the line
thus,
y  5 = 2(x  (1))
y = 2(x + 1) + 5
y = 2x + 2 + 5
y = 2x + 7
hope this helps` :) 
write y3=5(x+1) in slopeintercept form ?

Note that slopeintercept form is in the form
y = mx + b
where
m = slope
b = yintercept
Thus,
y  3 = 5(x + 1)
y = 5x  5 + 3
y = 5x  2
