Solve the following system of linear equation by graphing: 6x+3y=-21 8x+4y=-16. Graph the linear equation by writing the equation in slope-intercept form:
Added by Valeria C.
Step 1
Equation 1: 6x + 3y = -21 Divide both sides by 3 to isolate y: 2x + y = -7 Subtract 2x from both sides: y = -2x - 7 Equation 2: 8x + 4y = -16 Divide both sides by 4 to isolate y: 2x + y = -4 Subtract 2x from both sides: y = -2x - 4 Now we have both equations in Show more…
