Question

Find the y-intercept of the following equation. Simplify your answer.

y = 5x + 2

Answer 1

Answer:

Slope=10.000/2.000=5.000

X- intercept= 2/5=0.4000

y-intercept = -2/1= -2.000

Step-by-step explanation:

Notice that when x = 0 the vaue of y is -2/1 so this line "cuts" the y axis at y=-2.00000

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-5x+2 = 0 and calculate its properties

Graph of a Straight Line :

y-intercept = -2/1

= -2.000
