A straight line has a gradient of 53 and its passes through the point (1,3), It’s intercept on the y-axis is
To find the intercept on the y-axis, we can use the formula for the equation of a straight line in slope-intercept form:
y = mx + b
where m is the gradient and b is the y-intercept.
So, we have the gradient m = 53 and a point (1,3) that lies on the line. Let's substitute these values into the formula:
3 = 53(1) + b
Simplifying this equation, we get:
3 = 53 + b
Now, we can solve for b:
b = 3 - 53
b = -50
Therefore, the y-intercept of the straight line is -50.
