In order to find which one of the given points is a solution to the equation, we need to plug each point in the equation and check which one fits in .
The equation is :
5x+2y=-9
a.(2,-4)
5x+2y=-9
LHS: 5x+2y
Plugging (2,-4) in this,
5(2) +2(-4) = 10-8 =2
RHS : -9
LHS ≠RHS
So (2,-4) is not the solution.
b.(-1,2)
5x+2y=-9
LHS: 5x+2y
Plugging (-1,2) in this,
5(-1) +2(2) = -5+4 =-1
RHS : -9
LHS ≠RHS
So (-1,2) is not the solution.
c.(-2,5)
5x+2y=-9
LHS: 5x+2y
Plugging (-2,5) in this,
5(-2) +2(5) = -10+10 =0
RHS : -9
LHS ≠RHS
So (-2,5) is not the solution.
d.(1,-3)
5x+2y=-9
LHS: 5x+2y
Plugging (1,-3) in this,
5(1) +2(-3) = 5-6=-1
RHS : -9
LHS ≠RHS
So (1,-3) is not the solution.
None of the given options is a solution to the given equation.
Answer:
-1,3
Step-by-step explanation:
Answer:
Step-by-step explanation:
The rate of change of the function f(x) from point 
to point 
can be calculated using formula
Given
From the graph of the function
So, the rate of change is
Slope Intercept Form Equation: mx + b = y
Use the slope, like 3/2 or 4, but first plot the y-intercept, like 3, and then put the equation to these: y = 3/2x + 4 or y = 4x + 4. Plot the y-intercept on the y- axis (the vertical line). If you were to use my examples, you would plot the y-intercept by (0,4). Then if you used my first example equation, move 2 to the right of the plotted coordinates and then up by 3. If you were to use my second equation, however, then you would move to the left of the same plotted coordinates, (0,4), 1 to the right and then up 4.
There has to be a negative and a positive for each
