One way to find the y int is to sub in 0 for x and solve for y
-3x + 9y = -54
-3(0) + 9y = -54
9y = -54
y = -54/9
y = -6....so ur y int is -6 or (0,-6)
Answer:
For the parallel line it will still have a slpoe of 2/3
Step-by-step explanation:
as for the perpendicular line it will be double like 4/6 so it can meet it at a 90° angle.
Answer:
C
Step-by-step explanation:
36/60, now reduce.
9/15, reduce more
3/5, so 3.5 of the students chosen at random used a calculator for computation.
Answer:
slope: 5/7
0.714 mile per hour
Step-by-step explanation:
slope: find the point where the line is right on the line graph, put y/x which is 10/14 make the fraction smaller which is 10/14 = 5/7(I divide the denominator and nominator by 2)
Mile per hour: 5/7 cross multiply with x/1, make into an equation:
7x=5 x 1
7x = 5
x = 0.714
