What is the x-intercept of the equation y = 5x + 3

A. -5
B. -5/3
C. 3/5
D. 5/3
Thank you so much.

Definition of an x intercept is the point at which the graph crosses the x-axis.
We also know that no matter where you are on the x-axis, the y value is always 0.

Let's use this knowledge to our advantage.

We're looking for the point on y = 5x + 3 where y = 0. So plug 0 in for y.

0 = 5x + 3
5x = -3
x = -3/5

So the answer is none of the above because you either wrote your equation wrong, or one of your answer choices.

To find the x-intercept, set y equal to 0 and solve for x:
y = 5x + 3
5x + 3 = 0
5x = -3
x = -3/5

So, the answer is -3/5.

Hope that helps :)

The x-intercept is where the graph cuts the x axis. So y =0
Substituting in y = 5x + 3
0 = 5x + 3
-3 = 5x
-3/5 = x
x = -3/5

mmm?

The answer is B. To find this, let y=0 and the solve for x.

x intercept is when y = 0

0 = 5x +3
-3 = 5x
-3/5 = x

you don't have the answer there.
