Slope= 1/2


y-intercept = ????

Answer 2

Lines are in the form y = m(x)+b

where m is the slope.

in our line we have m = (1/2) right?

but to find the y intercept we need to set x = 0, or rather plug in x = 0 into our equation.

let's do that.

y = 0.5(x)-5

y = 0.5(0)-5 = 0-5

y = -5

so our y intercept would be -5, why? because this is the point where our function touches the y axis at -5 when x is zero.

sometimes the b value gives us the y intercept.

Answer 3

The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.
