The slope is the change in y-axis to x-axis of a graph. The slope of the line given is -10
<h3>How to find the slope of a line?</h3>
The standard equation of a line in slope intercept form is given as y = mx+b
where
- m is the slope
- b is the y-intercept
Given the equation y = -10x - 2
Compare
mx = -10x
m = -10
Hence the slope of the line given is -10

Answer:
85/100 = x/20
100x = 1700
x = 17 questions she answered correctly
x + 17 = 20
x = 3 questions she answered incorrectly

Answer:
1/3
Step-by-step explanation:
You need to use slope formula. (the change in Y over the change in X = Slope [x1-x2/y1-y2 = slope]). I believe you can also use point slope formula, but I forgot how to do that one.
First, you would set up the equation.
7-9/-2-4 OR 9-7/4+2
you would then solve to get
-2/-6 OR 2/6
when simplified you get
1/3
for both. Hope it helps!
Answer:
-12x+12y=0
Step-by-step explanation:
4x+15y=13 (1)
3x+5y=16 (2)
(2) * 3 --> 9x+15y=48 becomes (3)
(3) - (1)
5x=35
x=7
sub x =7 into (1)
4(7)+15y=13
28+15y=13
-28 -28
15y= -15
y= -15/15
y= -1
therefore x=7 and y= -1
