Question

Which of the following is the equation of a line in slope intercept form for a line with slope = 5 and y intercept at 0, -3?

Answer 1

y = 5x - 3 is the answer I got

Answer 2

The correct option is c

Explanation:

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where c = intercept

Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis.

From the information given, we would find the value of the intercept, c by substituting m= 5, y = - 3, x = 0 into the slope intercept equation. y = mx + c. It becomes

- 3 = 5×0 + c

c = - 3.

The equation in the slope intercept form becomes

y = 5x - 3
