Question 54551
Resolution:
first you need to find two points in order to find the slope.
x-intercept is 3; this mean that the x interception point is (3,0)
y-intercept is 5; this mean that the y interception point is (0,5)

now you have two points (3,0); (0,5)

the slope formula is m = (y - y1)/(x - x1) replace values:

(5 - 0)/(0 -3); 5/-3; so the slope is m = -5/3.

the slope-intercept is y = mx + b; pick point (0,5) and replace values in the formula. y = -5/3(x) + b where b is the y intercept.
