Question 517642
find the x and y intercept and graph the equation plotting the intercepts. please show all work. -5x+8y=-40
**
standard form of equation for a straight line: y=mx+b, m=slope, b=y-intercept
for given equation:
-5x+8y=-40
8y=5x-40
divide by 8
y=5x/8-40/8
y=5x/8-5
y-intercept=-5
..
finding x-intercept
set y=0
0=5x/8-5
5x/8=5
5x=40
x=8
see graph below:
