Answer:
5x+3y=8.50 and 3x+2y=5.25
Step-by-step explanation:
because i got it correct
Answer:
Step-by-step explanation:
y = x - 5
2x - 5y = 1
2x - 5(x - 5) = 1
2x - 5x + 25 = 1
-3x + 25 = 1
-3x = -24
x = 8
y = 8 - 5
y = 3
(8, 3)

Answer:
y = -9 / 7x + 109 / 7
Step-by-step explanation:
To find the equation of any line, you must find the slope and y-intercept (when writing in slope-intercept form). In this case, we can find both of these values by using the two coordinate pairs that are given:
Slope - the change in y over the change in x
- 9 / -7 = -9 / 7
- slope = -9 / 7
- y-intercept - when x = 0
Right now, since we have the slope, we know the equation will look like this: y = -9 / 7x + b, b is what we are trying to find, the y-intercept. To find b, we can substitute a given coordinate pair that we know will fit this line and then solve:
- 13 = -9 / 7 x 2 + b
- 13 = -18 / 7 + b
- 91 / 7 + 18 / 7 = b
- 109 / 7 = b
After finding both the slope and y-intercept, we can now combine them together to form the equation of the line:
y = -9 / 7x + 109 / 7
Hope this helps!!
