gradient, 2. If the equation of a straight line is written in the form m, and the y-intercept, c, can be determined directly from the y = mx + c, the equation.

Given that the equation of a straight line is y = 3 - 4 x. Find the gradient and y-intercept of the line?

Therefore, gradient, m = - 4

change it to the form 3. If the equation of a straight line is written in the form y = y-intercept. mx + c before finding the gradient and the ax + by + c = 0,

Given that the equation of a straight line is 4 x + 6 y- 3 = 0. What is the gradient and Solution: y-intercept of the line?

Given that the equation of a straight line is 4 x + 6 y - 3 = 0. What is the gradient of the line?

Given that the equation of a straight line is y = - 7 x + 3. Find the y-intercept of the line?

y = m x + c, c is y-intercept of the straight line.

Therefore for the straight line y = - 7 x + 3,
