Answer:
B and C
Step-by-step explanation:
They are on the same line so they ad up to 180 and are supplementary
The best way to figure this out is to rewrite the equation in to standard slope form:
y = mx + b
this would look like...
5y = -7x + 35
divide 5 from each side of the equation...
-7
y = —— x + 7
5
find the values you can graph...
b = y intercept = the point in which the line "hits" the y axis on the graph. so count 7 points up and plot a point on the y axis at 7.
once you plot that, this is the starting point of your slope...
-7 (rise) count 7 down
m = slope = —— (over)
5 (run) count 5 to the right

5: 5, 10, 15, 20, 25, 30, 35, 40
10: 10, 20, 30, 40
least common multiple is 10
5.4 because the 9 bumps it to 5.35.
And the 5 bumps it to 5.4.
