The solution is, the slope of the line in the graph is 5/7.
What is slope?In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
here, we have,
from the given graph, we get,
the line is passing through the points ( 0,0) and, (5,7).
now, we know that
slope of a line is,
m = x1 - x2 / y1 - y2
so, we have,
here,
Slope(m) = 5-0/7-0
= 5/7
Hence, The solution is, the slope of the line in the graph is 5/7.

Determine what comes next in the given pattern 41,39,37,35,33
Answer:
31
Step-by-step explanation:
you're just subtracting by two's as the pattern goes on.
In the given pattern 41,39,37,35,33,the next number in the pattern is 31. To determine what comes next in the given pattern,let's observe the sequence:
41, 39, 37, 35, 33
The pattern is a decreasing sequence where each number is subtracted by 2 to get the next number.
So, to find the next number, subtract 2 from the last number in the sequence: 33 - 2 = 31
The next number in the pattern is 31.

Answer:
x=-5
Step-by-step explanation:
-5*-3=15
15-2=13
Hope it helps
Answer:
x = -5
Step-by-step explanation:
-3x-2=13
Add 2 to both sides of the equation
-3x-2+2=13+2
Simplify
-3x=15
Divide both sides of the equation by the same term
[tex]\frac{-3x}{3} =\frac{15}{-3}[/tex]
Simplify
x = -5
Write the slope-intercept equation of the line passing through (4,6) and (0,-8).
Answer:
Answer:
[tex]y=\frac{7}{2} x -8[/tex]
Step-by-step explanation:
We are given that a line contains these 2 points: (4,6) and (0,-8), in slope-intercept form
Slope-intercept form is given as y=mx+b, where m is the slope and b is the value of y at the y intercept
First, we need to find the slope of the line
The slope can be calculated using the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points
Even though we have 2 points, let's label their values to avoid any confusion and mistakes when calculating:
[tex]x_1=4\\y_1=6\\x_2=0\\y_2=-8[/tex]
Now substitute into the formula
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m=[tex]\frac{-8-6}{0-4}[/tex]
Subtract
m=[tex]\frac{-14}{-4}[/tex]
Divide
m=[tex]\frac{7}{2}[/tex]
The slope is 7/2
Here is the equation of the line so far:
[tex]y=\frac{7}{2}x + b[/tex]
We now need to find b
As the equation passes through (4,6) and (0,-8), we can use either one of them to help solve for b.
Taking (4,6) for instance:
[tex]6=\frac{7}{2}(4) + b[/tex]
Multiply
[tex]6=14 + b[/tex]
Subtract
-8 = b
The equation therefore is:
[tex]y=\frac{7}{2} x -8[/tex]
