Answer: y=1/4x+4.75
Step-by-step explanation:
first you take the coordinate and slope and put it into point slope form (y-y1=m(x-x1) so your equation would become y-3=1/4(x+7). the 7 became a plus because two negatives equals a positive. you then simplify the equation and it should become "y-3=1/4x+1.75" to get the y by itself you add three to 1.75 and then you have slope intercept form.
edit: sorry i used a decimal instead of the fraction but just convert the decimal to a fraction :)
