slope is 4
x - intercept (13/4,0)
y- intercept (0,-13)

Explanation:

to get the slope, we need to change the equation in to the form of y=mx+b , m = slope

4x-y = 13
y=4x-13
m=4
m or slope is the coefficient of the term containing x

for the intercepts,

by definition x- intercept means the point that lies of the x axis
and y- intercept means the points on the y axis

so for the x- intercept,
just substitute y to 0, then solve for x

4x-y=13
4x-0=13
x=13/4

x - intercept (13/4,0)

for the y- intercept
just substitute x to 0, then solve for y
4x-y=13
4(0)-y
y=-13

y- intercept (0,-13)
