Since you are given the points of the line then you'll have the slope as:
m =  \frac{x_2 - x_1}{y_2-y_1}
substituting the points (0,5) and (-5,0)
m =  \frac{5-0}{0-(-5)} m = 1
substituting the slope and the point(-3,5) you'll have
m = \frac{x_2 - x_1}{y_2-y_1}
1 = \frac{x - (-3)}{y - 5}
y - 5 = x + 3
y - x = 3 + 5
y - x = 8
or in slope-intercept form
y = x + 8
