Answer:

y=-1/4x+1

Step-by-step explanation:

Hi there!

We're given the point (-8,3) and a slope of -1/4

lines are typically written in the formula y=mx+b, where m is the slope and b is the y intercept

as we are already given the slope, we can substitute its value into the equation

substitute -1/4 as m

y=-1/4x+b

now we need to find b

as the equation passes through the point (-8,3),we can use it to solve for b

substitute -8 as x and 3 as y

3=-1/4(-8)+b

multiply

3=2+b

subtract 2 from both sides

1=b

substitute 1 as b

y=-1/4x+1
