Question

Y=5x+5 is the equation of a straight line graph. What is its gradient?

Answer 1

5

Explanation:

The equation of a straight line is :

y=mx+c

where m is the gradient and c is the y-intercept

so if m equals 5 then the gradient is 5

Answer 2

gradient = 5

Explanation:

The gradient is the coefficient of x, so for y = 5x + 5 it is 5.

(the +5 part is the y-intercept, i.e. where x = 0)
