## anonymous one year ago Help: What is the equation of a line that passes through (4, 7) and has a slope of −14? y=x4−74 y=−x4+74 y=−x4+8 y=x4+8

1. MrNood

I think you have typed this wrong is the slope -4 (or -14) answers would normally be something like y=-14x +10 why are they written y = x4 ....?

What is the equation of a line that passes through (4, 7) and has a slope of −1/4? y=x/4−7/4 y=−x/4+7/4 y=−x/4+8 y=x/4+8

sorry they where all fractions

4. MrNood

ok - that is better so - a straight line has an equation y=mx+b where m and b are constant values m is the slope SO to start with: you know the slope is -1/4 which 2 answers have a slope of -1/4 ?

5. anonymous

a and b?

6. MrNood

|dw:1444132148614:dw| which have a value of -1/4 in front of the x?

7. anonymous

oh c and d

8. MrNood

no - it's not c+d look at teh value in front of the x that is the slope value you want to find the options where that value is -1/4

9. anonymous

so its c

10. MrNood

no Sorry - I can't see where teh difficulty is 2 of those answers have -1/4 in front of the x which are they? $\frac{ -x }{ 4 } = \frac{ -1 }{ 4 }x$
