Find the -intercept of the line whose equation is y = -3.7x4.2

Question

Find the -intercept of the line whose equation is y = -3.7x4.2

Answer 1

Do you mean y = -3.7x + 4.2?

 

If you mean the y-intercept, then plug in 0 for x and solve for y, because x is always 0 on the y-axis.

 

So y = -3.7x + 4.2 - 0 + 4.2 = 4.2

 

If you mean the x-intercept, then plug in 0 for y, because y is always 0 on the x-axis.

 

So 0 = -3.7x + 4.2

3.7x = 4.2

x = 4.2 / 3.7 = 1.135135...
