The line given to us is in the form y = mx + c , where m is the slope of the line and c is the y- intercept. So there is nothing to be done here.
Just take the coordinates from the equation.
y = 3 - 5x = -5x + 3
So m = -5 and c = 3
The required gradient of the line is -5 and the y- intercept of the line is 3
The equation for a line in the standard slope (or gradient) and intercept form is :
y = mx+c, where m is the gradient or slope measuring rate y inrement per x increment. c is the y intercept .
So the given line y = 3-5x , or y = (-5)x+3 scould be identifies with y = mx +c.
So m= -5 is the gradient. c = 3 is the y intercept, where the line y = 3-5x is intersecting the y axis.
