y=-4x+17

Explanation:

Given;
The line passes through the point J-=(4,1)
m=-4
intercept is given by
c=b-ma
where the line passes through (a,b)
a=4,b=1
c=1-(-4)xx4
c=1+16
c=17

Thus,
y=mx+c

y=-4x+17

y=-4x+17

Explanation:

"the equation of a line in "color(blue)"slope-intercept form" is.

•color(white)(x)y=mx+b

"where m is the slope and b the y-intercept"

"here "m=-4

rArry=-4x+blarrcolor(blue)"is the partial equation"

"to find b substitute "(4,1)" into the partial equation"

1=-16+brArrb=1+16=17

rArry=-4x+17larrcolor(red)"in slope-intercept form"
