My "work" is to enter the equations into a graphing calculator and let it show me the answers--just as your "work" is to copy the question to Brainly.
The solutions are
(x, y) = (-0.5, 7.5)
(x, y) = (3, 25)
_____
When you equate the expressions for y, you get the quadratic
2x² -5x -3 = 0
(2x +1)(x -3) = 0
x = -1/2 or 3
y = 5(x +2) = 15/2 or 25

1: Assuming this line is linear, the first thing to do is find the slope.
The slope formula is
, so in this case, it is 
, which comes to 
. Then, use your slope and one of the points given to write the point-slope formula of the linear equation, and then written in standard form:
y=x-
.
2. Use the same process as in question 1 to find:
y=-7x+11
The slope formula is
y=

y=-7x+11
