500
Convert 6x+2y=10 to slope-intercept form:
y=-3x+5
500
Is this the correct graph for y=3x+2? Why?
yes, the y-intercept is at (0, 2) and the line is increasing at a positive rate by going up 3 and over 1

y=2x-5
600
Is this the correct graph for y-5=7(x+3)? Why?
no, the coordinate point (-3, 5) is correct but the slope is wrong, instead of graphing up 7 over 1 it is up 1 over 7
