Complete the equations of the system in slope-intercept form. Use a decimal for the slope if necessary. Line 1 x y 0 3 1 5 Line 2 x y –1 1 –2 –1 Line 1: y = x + Line 2: y = x + @perl .......i have no idea

    First start with the slope formula of m=(y2-y1)/(x2-x1)

    And then for line 1 you already know the y intercept so y=mx+b should be easier to figure out

    Ok for slope formula. y2-y1=5-3 and the. You divide that by x2-x1 which equals 1-0. So the slope for line 1 is m=2/1=2.

    line 1 slope: $$\Large {m=\frac{5-3}{1-0}} $$

    Once you find out the slope like perl gave a good illustration for, look at the ordered pairs. Do you have an x that is 0? Well we know that for lines the y intercept is (0,y)

    the y intercept is the point (0,b)

    m = 2 y intercept b is 3 y = mx + b now put it together
