Answer:
[tex]y=4x+3[/tex]
Step-by-step explanation:
To find the equation of this line, we must use the point slope formula.
[tex]y-y_1=m(x-x_1)[/tex]
[tex]x_1[/tex] is the x coordinate
[tex]y_1[/tex] is the y coordinate
m is the slope
We have a slope of 4 through the point (0,3)
[tex]y-3=4(x-0)\\\\y-3=4x\\\\y=4x+3[/tex]
