Answer:

A: y = 2x - 3

Step-by-step explanation:

Slope (m) formula: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

I will be using (0,-3) and (4, 5) to find the slope:

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{5-(-3)}{4-0}\\\\m=\frac{5+3}{4-0} \\\\m=\frac{8}{2}\\\\m=4[/tex]

(0,-3)

[tex]y=mx+b[/tex]

[tex]y=2x+b[/tex]

[tex]-3=2(0)+b\\\\-3=0+b\\\\-3=b[/tex]

[tex]y=2x-3[/tex]

Hope this helps!
