Final answer:

To write the equation of a line passing through (-1, 1) parallel to y = -3/4x - 5, we use the same slope of -3/4. By substituting the point into the slope-intercept form and solving for the y-intercept, we find the y-intercept to be 1/4, yielding the equation y = -3/4x + 1/4.

Step-by-step explanation:

The slope-intercept form of the equation of a line is given by y = mx + b, where m is the slope of the line and b is the y-intercept. To write the equation of a line that passes through the point (-1, 1) and is parallel to the line described by y = -3/4x - 5, we need to use the same slope since parallel lines have equal slopes. Hence, the slope m will be -3/4. To find the y-intercept b, we use the given point and the slope in the slope-intercept form:



y - y1 = m(x - x1)



Here, (x1, y1) is the point (-1, 1). Plugging these values in gives:



1 = (-3/4)(-1) + b



By solving for b, we get:



b = 1 - 3/4



b = 1/4



Therefore, the equation of the line is y = -3/4x + 1/4.
