why is math so hard
somehow i am supposed to turn x - 7y = 4 into slope-intercept form
and after i have that i am supposed to plug in into another equation but i have no idea what im doing
someone pray for me.
Slope-intercept form is y = mx + b where m= slope and b = y-axi intercept
So solve your equation, x - 7y = 4 for 'y'
x-7y =4 Add 7 y and subtract 4 from both sides
x-4 =7y rearrange for ease
7y=x-4 Now divide both sides by 7
y = 1/7 x - 4/7 there it is.... m= slope = 1/7 and b= -4/7
