Answer

point-slope form $y+4=3(x-1)$ slope-intercept form $y=3x-7$

Work Step by Step

Step 1. The given line $3x-y+5=0$ has a slope of $m=3$ Step 2. The unknown line is parallel to the above line and its slope is the same. Step 3. We can write the point-slope form as $y+4=3(x-1)$ Step 4. We can rewrite the above in slope-intercept form as $y=3x-7$
