One strategy is to graph the two points and make a slope triangle to find the slope of the line.
Use the slope triangle to find the slope of this line.
Substitute a pair of coordinates for x and y and the slope to solve for b.
y = mx + b
10 = −3(5) + b
10 = −15 + b
25 = b
Substitute the values found for m and b into the equation of the line.
