Answer:

7x = y + 37

Step-by-step explanation:

y = 7x - 9

Differentiating y with respect to x, we have as follows:

dy/dx = m = 7 ( where m is the slope)

Using the formula y - y1 = m(x - x1) to obtain the equation of line passing through point (4.-9)

y + 9 = 7(x - 4)

y + 9 = 7x - 28

∴ 7x = y + 37

Daniel and Sofia both solve this system of equations:
Evgesh-ka [11]

Answer:

Sofias solution is correct.

Step-by-step explanation:

First of all you do not need two sets of the same equation.


y=-1.5x + 5.7

y = 0.5x + 0.3


If you graph the y-intercepts first then graph the slope for the equation then you will get the right answer.

1) Graph 5.7 on the y-axis. | Then graph -1.5x going down on the y-axis and then go to the right on the x-axis.

Do the same for the other equation and you will get a solution of (2.7, 1.65) since they will intersect there.
