Answer:
x intercept is (45/2,0)
y intercept is (0,-36)
Step-by-step explanation:
Slope intercept form of equation of line is
y=mx+b where m is the slope and b is the y intercept
use any two points to find the slope
(10,20) (15,12)
m = -8/5
now we find out b using (10,20)
20 = -16 + b
add 16 on both sides , so b = 36
b is the y intercept , so y intercept is (0,-36)
Now we find x intercept
equation of line is y=mx+b that is
To find x intercept plug in 0 for y
subtract 36 on both sides
Multiply by -5/8 on both sides
x intercept is (45/2,0)
