help
firstly, if two lines are parallel, they have the same slope
so which two choices can you eliminate?
this fat cat says C
you can eliminate another too
this fat cat says B
nope
the slope has to be -3
This fat cat does not understand this
y = mx + b where m is the slope
the equation y = -3x + 7 means that the slope is negative 3 and the y-intercept is 7
this fat cat says he sees no slope
parallel lines have the same slope the slope of y= -3x + 7 is -3 the slope of y = 3x + 14 is 3 the slope of y = -3x + 2 is -3 the slope of y =1/3 x + 4 2/3 is 1/3 the slope of y= -3x + 10 is -3 so which equations have a slope of -3...
This fat cat says B
This fat cat says also D
Yeah so slope is -3 Now we have to find the y-intercept using the slope and the coordinate point substitute the x y values into the equation (2,-4) y=mx+ b -4 = -3(2) + b can you solve for b?
no
what is -3 times 2
-6?
yes so -4 = -6 + b what is -4 plus 6
2?
yes the b is 2 the equation is y = -3x + 2
b is correcto?
si
gracias c;
de nada
