How would you graph the following systems of equations ? <br><br> y= -3x -7<br> x- 2y=-14
andrey2020 [161]
Solve both formulas to y=mx+b (slope intercept formula) where m=slope and b=y-intercept

y=-3/1x+-7

x-2y=-14
-2y=-14-x
y=7+1/2x

Start with the b variable so for problem 1 put a dot on 0,-7 and for problem 2 put a dot on 0,7

Then from -7 for problem 1 depending on whether the slope is negative or positive go down 3 and over right 1 therefore another point for problem one is marked, at 1,-10; for problem 2 up 1 and to the right 2; 2,8

For problem one connect the dots of 0,-7 and 1,-10

For problem two connect the dots of 0,7 and 2,8
