Please i need help realy fast or i will fail this semester

A pair of linear equations is shown below:
y = -2x + 3

y = -4x - 1

Which of the following statements best explains the steps to solve the pair of equations graphically?


Graph the first equation which has slope = 3 and y intercept = -2; graph the second equation which has slope = -1 and y intercept = -4 and find the point of intersection of the two lines.

This is my best choice: Graph the first equation which has slope = -2 and y intercept = 3; graph the second equation which has slope = -4 and y intercept = -1 and find the point of intersection of the two lines.

y=mx+b
m=slope
b=yintercept

given
y=-2x+3 and
y=-4x-1

first equation is slope -2 and yintercept 3
second is slope -4 and yintercept -1

3rd option
