to graph a LINEar equation, since it's just a straight line, recall, to draw a straight line all you need is two points.
so we can just pick two random "x" values, hmmmmm say x = 0, what's "y"?
y = 7(0)-7 => y = -7....................................... so that gives us the point (0, -7)
hmmm x = 2, what is "y"?
y = 7(2) - 7 => y = 14-7 => y = 7................. so we get the point (2, 7).
then just plot those, and run a line through them.
 
        
             
        
        
        
So in 10 days the grasshopper (x) is doubled (2x)
20 days it is 2(2x) or 4x
30 days it is 2(4x) or 8x
in 35 days it is 1/2 of 10 so 1/2 times 2 times 8x=8x
it increased by a factor of 8
        
                    
             
        
        
        
Slope of the equation is -9/2
Step-by-step explanation:
- Step 1: Write the equation in slope-intercept form y = mx + b
 
9x + 2y = 9
2y = -9x + 9
y = -9/2 x + 9/2
⇒ Slope, m = -9/2
 
        
             
        
        
        
Answer: a c d 
Step-by-step explanation: they are functions because the line is intersecting points as well as being squared cubes and a is a absolute value function
 
        
             
        
        
        
Answer:
Slope-Intercept form:   y = m x + b
y = value of y corresponding to value of x
2 y = 10 x - 6
y = 5 x - 3         equation of line where m is the slope and -3 value of y when x                       
                          equals  zero
