What is the equation of the line that passes through (1, 2) and is parallel to the line whose equation is 2x + y - 1 = 0?

Hello : 
an equation is : 
y -  2 = -2(x-1)(a line parallel to the line y = -2x + 1 ' same slope : -2)
y = -2x+4

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.

Ithink the answer is discovery verbs because they are quite similar to the verb 'discovering'
