Question

Equation of a line is y = 2x + 5

a) what is the gradient?

b)what is y- intercepted?

c) if the gradient is -3 and y-intercept is 1,then what is the equation of the line?

Answer 1

Explanation:

Generally, we have the equation of a straight line as;

y = mx + b

where m is the slope and g is y intercept

a) The gradient is the slope and we have the value as 2

b) The y-intercept here is 5

c) for slope -3 and intercept 1, the equation becomes

y = -3x + 1
