with what and ill help you

The description below represents Function A and the table represents Function B: Function A The function is 5 more than 3 times x. Function B |dw:1405548532391:dw| Which statement is correct about the slope and y-intercept of the two functions? Their slopes are equal but y-intercepts are not equal. Their slopes are not equal but y-intercepts are equal. Both slopes and y-intercepts are equal. Neither slopes nor y-intercepts are equal.

ok lemme see :)

nice drawing = )

OpenStudy (camerondoherty):

the equation for Function A is f(x)=3x+5

OpenStudy (camerondoherty):

thanx

OpenStudy (camerondoherty):

So that means the slope of Equation a is 3

i used slope intercept formula to figure out the function b so y-intercept is (0,y) that 0 is always there whenever we're talking about y-intercept. we know from the function b that one coordinate is (0,5) so we plug that into the slope intercept form y=mx+5 we are also given another point (1,8) We can plug that into our equation 8=m(1)+5 then, solve for m 8-5=3 m=3 so the equation for function b is y=3x+5

OpenStudy (camerondoherty):

So its C

OpenStudy (camerondoherty):

Thanx

yes :P
