Slope intercept form is y=mx+b. since there is no b term, the y intercept is 0. since there is a 9 in the m term, your slope will be nine. based on those two things, you need a point at (0,0) and (1,9). on the other end, your point will be (-1,-9). then draw a straight line through. hope this helps :)
Sorry no i cant have a great day tho
Answer:
(7, 0).
Step-by-step explanation:
We have y = 3(x - 7)
y = 3x - 21
Point-slope form is
y - y1 = 3(x - x1)
y - y1 = 3x - 3x1
Comparing this to the equation y = 4x - 21 we see that y1 = 0 and x1 = 7.
Answer:
y = 1/2 x - 4
Step-by-step explanation:
slope of perpendicular line is 1/2
y +3 = 1/2 (x -2)
y + 3 = 1/2x - 1
y = 1/2x - 4

19. 85%
Work for 19:
The chart is incorrect because it calculates 40% of 34 instead of 40 percent of x (we got 85% for our answer but I'm using x as the unknown number) results in the number of 34.
Percentage of 40% of what number = 34?
40% of what number = 34 is equivalent to: 40% × ? = 34
--------------------------
40% × ? = 34
? =
34 ÷ 40% =
34 ÷ (40 ÷ 100) =
(100 × 34) ÷ 40 =
3,400 ÷ 40 =
85
Proof:
If 40% × 85 = 34 =>
Divide 34 by 85...
... And see if we get as a result: 40%
