The slope of the line l is the opposite reciprocal of y+2x=9. Rearranged the equation to y=9-2x and we get a slope of -2. The opposite reciprocal of -2 is 1/2.
y-y=m(x-x)
y-3=.5(x-4)
y=.5x+1
At the x-intercept, y=0, so
0=.5x+1
-1=.5x
x=-2
Answer:
B. You have to distribute properties. So you distribute the exponent 5 to both the 6 & the 9
The answer is 10 because 5 10 15 20 25 30 35 40 45 50
