- Slope-Intercept Form: y = mx + b, with m = slope and b = y-intercept
- Slope Formula:
So firstly, to find the slope of this equation, plug the two points, (1,1) and (-3,2), into the slope formula and solve as such:
Next, plug either one of the points into the x and y coordinates to solve for b as such:
<u>Our final equation is 
, or the third option.</u>
X int can be found by subbing in 0 for y and solving for x
9x - 7y = 21
9x - 7(0) = 21
9x = 21
x = 21/9 which reduces to 7/3...so the x int is 7/3 or (7/3,0) <==
to find the y int, sub in 0 for x and solve for y
9x - 7y = 21
9(0) - 7y = 21
-7y = 21
y = -21/7
y = -3....so the y int is -3 or (0,-3) <==

Answer: y = 2x + 3. 4x - 3y = 2. (A.K.A 6)
Step-by-step explanation: What is the value of the x-coordinate of the point of ... We can solve the system of equations by substituting the value of y from the second equation into the first. y = 2x + ... Thus, the second and third lines intersect at (-11/2,-8). ... 6y - 3x = -6: 4x - 5y + (6y - 3x) = 12 + (-6). 4x - 3x + 6y - 5y = 12 - 6. x + y = 6.
