4/3 or 4 are in 2/3 and 3
If you are given 2 points, it's easy to find the slope.
(8, -6)
(3, -2)
slope = (y₂ - y₁) / (x₂ - x₁)
slope = (-2 + 6) / (3 - 8)
slope = (4) / (-5)
m = 4/-5 or -5/4 or
If we have the equation of a line: y=ax+b
How to find a if with only the x<span>-intercepts (called m)</span> and y-intercepts (called n)
+ First we have y=0 and x=m or 0=a*m+b or b= -a*m
+ Then we have x=0, y=n or n=a*0+b or b=n
And if m≠0 we have a= -n/m
and if m=0 this line has no slope
The number or (x) is 4.I hopes this helps you with your work <3
Answer:
y ≤-1/2 x-1
y < -4x+25
Step-by-step explanation:
The y intercept is -1
The slope is negative since the line goes down from left to right
The line is y = -1/2 x -1
The line is solid so there is an equals in the inequality
The graph is shaded below the line
y ≤-1/2 x-1
Question 5
The y intercept is 25
The slope is negative since the line goes down from left to right
The slope is (y2-y1)/ (x2-x1) = (49-25)/(-6-0) = 24/-6 = -4
The line is y = -4 x +25
The line is dotted so there is NOT an equals in the inequality
The graph is shaded below the line
y < -4x+25
