Write the equation of a line that is parallel to y = -x + 7 and passes through the point (-4, 1). Write your answer
in slope-intercept form, y = mx + b.

y= -x-3

Step-by-step explanation:

A line is parallel to another line if their slope is the same. In this case the slope is -1 (-x is basically -1x). So far we have y=-x+b (We dont know what b is yet). next we can insert the coordinate back into the equation y=-x+b where 1 is the y and -4 is the x.

We get...

y= -x+b

1= -(-4)+b

1=4+b

b=-3

Our final equation is y=-x-3

1) a: [$]75 + [$]0.20x = ƒ(m) b: [$]0.35x = ƒ(m)the 75 is how much you automatically pay and the .2x and .35x is how much you would pay per mile (the variable can be changed to your liking). ƒ(m) is the total cost. 2) set your equations to equal each other.75 + .2x = .35xsolve.move the .2x over by subtracting it from both sides. 75 = .15xget x by itself by dividing both sides by 0.15.500 = xit would take 500 miles for plan a and b to be equal in cost.
