Find the slope using the formula [ y2-y1/x2-x1 ].
-9-(-12)/-15-(-24)
3/9
1/3
Find the y-intercept using the formula [ y = mx + b ].
y = 1/3x + b
-12 = 1/3(-24) + b
-12 = -8 + b
-4 = b
Use (18, 2) to see if the line passes through it
y = 1/3x - 4
2 = 1/3(18) - 4
2 = 6 - 4
2 = 2 TRUE
Thus, the line does pass through (18, 2).
Best of Luck!
4) 41% of 78 is what?
Answer = 31.98
Work:
x = 41/100 x 78
x = 3198/100
x = 31.98
6) 58% of what is 63.4?
The number is = 109.31
Explanation:
Let the number be = x
58/100 (x) = 63.4
x = 63.4 x (100/58)
x = 6340/58
x = 109.31
Answer:
39 is the answer
Step-by-step explanation:
well so in this is it a little tricky so yea let me see got it right
<span>3x+2y=13.95
3x+4y=18.33
-1(3x+2y=13.95)
-3x-2y=-13.95
</span>-3x-2y=-13.95
3x+4y=18.33
2y = 4.38
y = 2.19
y = 2.2
