Answer:
y-5x-7=0
Step-by-step explanation:
m = -2-3/1-2
m=5
y-y1 = m(x-x1)
y-2=5(x+3)
y-2=5x +5
y-5x-7=0
Answer:
m = -32.10
Step-by-step explanation:
You solve this the same way you do any two-step linear equation.
1. Subtract the constant that is on the side of the equal sign with the variable term:
m/5 = -6.42
2. Multiply by the inverse of the coefficient of the variable. That means multiply by 5 in this case.
m = 5·(-6.42) = -32.10
_____
Of course, the rules of equality tell you whatever you do to one side of the equation must also be done to the other side. So, when we say subtract 0.12, we mean subtract 0.12 from both sides of the equation. The same for multiplication or division.
Answer:
Check the explanation.
Step-by-step explanation:
As the graph of a linear function f passes through the point (-2,-10) and has a slope of 5/2.
As the slop-intercept form is given by:

where m is the slope and b is the y-intercept.
substituting the values (-2, -10) and m = 5/2 in the slop-intercept form to determine y-intercept.






And the equation of the line in the slope-intercept form will be:

putting b = -5 and slope = m = 5/2



Determining the zero of function.
As we know that the real zero of a function is the x‐intercept(s) of the graph of the function.
so let us determine the value of x (zero of function) by setting y = 0.





Therefore, the zeros of the function will be:
To solve this problem, set up and solve a system of equations. The variables b and m will represent a bread loaf and milk jug, respectively:

I would solve using substitution. Take one of the equations and set it equal to one of the variables, for example:

Now, plug this into the other equation for m and solve for b:

We now know that a loaf of bread costs $2.50. Plug this value in for b in the first equation and solve for m:

One jug of milk costs $1.50 and one loaf of bread costs $2.50.
