Please help me. Sketch the following two graphs on the same axis. Show calculations. A:y=-3x+3and B: 4y-5x+20=0 and determine the coordinates of the intersection point of the two graphs.
u got to do them in a paper then answer
sorry can't help on this
A: y-intercept 3; slope -3 B: 4y = 5x -20 y 5/4 x - 5 y-intercept -5; slope 5/4
it is correct so y r u asking
rickchickenheart. Thanks. I got the intercepts of A (1:0) and (0:3) and B (4:0) and (0:-5). ow do I calculate the coordinates of the intersection point of the two graphs?
the easiest thing to do here seems to me to plug in the value for of the first equation into the second eg. 4y = 5x - 20 <=> 4(-3x +3) = 5x - 20 <=> -12x + 12 = 5x - 20 now solve for x after that plug the found value for x in the first equation
Thank you. HAVE A NICE EVENING. Tiaan.
you're welcome
