y=mx+b
M is also slope. b= y-intercept
9x + 10y = 91
move 9x to the other side
sign changes from +9x to- 9x
9x-9x+10y=-9x+91
10y=-9x+91
Divide both sides by 10 to get y by itself
10y/10=-9/10x+91/10
y=-9/10x+91/10
y-intercept (x=0)
9x + 10y = 91
9(0)+10y=91
0+10y=91
10y=91
Divide both sides by 10
10y/10=91/10
y=91/10
Answer:
slope (m)=-9/10
y-intercept :(0, 91/10)
