Just divide 3 and 20.
        
                    
             
        
        
        
<u>Answer:</u>

gradient = = 
y-intercept = 
<u>Step-by-step explanation:</u>
• The slope-intercept form of an equation takes the general form:
 ,
,
where:
m = slope,
c = y-intercept.
• We are given the equation:

To change this into the slope-intercept form, we must make y the subject:
 [subtract
          [subtract  from both sides]
 from both sides]
⇒  [divide both sides by 3]
        [divide both sides by 3]
⇒ 
• Comparing this equation with the general form equation, we see that:
m = 
c =  .
.
This means that the gradient is  , and the y-intercept is
, and the y-intercept is  .
.
 
        
             
        
        
        
The rule to remember about generating the perpendicular family to a line is we swap the coefficients on and x and y, remembering to negate one of them. Then the constant is set directly from the intersecting point.
So we have
y = 3x + 2
-3x + 1y = 2
Swapping and negating gets the perpendiculars; the constant is as yet undetermined.
1x + 3y = constant
Since we want to go through (0,2), we could have just written
x + 3y = 0 + 3(2) = 6
3y = -x + 6
y = (-1/3) x + 2

Answer:
Step-by-step explanation:
b would be 0
your slope is rise/run. up one and over three. up one and over three. so 1/3
write it as y=1/3x+0, or y=1/3x
 
        
             
        
        
        
A. you would put in 7 for X and 3 for Y.
3 + 7 = 10
2(10) = 20
