Write the equation of the line with a slope of -5 and y-intercept of 12.

y=-5x+12

Step-by-step explanation:

Since slope-intercept form is y=mx+b, m is the slope, and b is the y-intercept. We substitute m for -5, since it is the slope, and we substitute 12 for b, since it is the y-intercept. I hope this helps!

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
