y=4x+17
Step-by-step explanationStep 1
2 equations of lines are parallel if the slope is the same, so
a) find the slope of the graphed line
the slope of a line can by calculated by using

so
pick up 2 points from the the line and let

replace and evaluate

hence, the slope of the line is 4
Step 2
now, using the slope and a point we can find the equation of the line
use the point-slope formula, it says

so
a)let

b) now ,replace and solve for y

so, the answer is
y=4x+17
