    Step-by-step explanation:

    The two lines intersect at 1,4 when you graph them

    The first equation is already in slope intercept from, so you know the y-int. is 7 and the slope is 3. However, the second equation must be put in slope int. form.

    5x+2y=3

    move the y to the other side

    5x=3-2y

    move the 3 to the other side, so the y variable is by itself

    5x-3=-2y

    divide by - 2 to the equation is equal to y

    (-5x/2) + (3/2) = y

    you now know the y int. of the second equation is 3/2 and the slope is - 5/2

    know that you know the slop int. formulas for both equations you can graph them
