Question

What is the x-coordinate of the x-intercept of the line that passes through points (-5, 3) and (1, -3)?
H-E-L-P

Answer 1

Using y=mx+c to make an equation. First by finding gradient,-3+3/1-(-5) = -1

Find the y-intercept(c) by using any point and
substitute into y=mx+c .
-3=-1(1)+c
c=-4

Thus the equation will be y=-x-4

When y=0,

-x-4=0
-x=4
x=-4

Hope this helps!

Answer 2

Using y=mx+c to make an equation. First by finding gradient,-3+3/1-(-5) = -1

Find the y-intercept(c) by using any point and
substitute into y=mx+c .
-3=-1(1)+c
c=-4

Thus the equation will be y=-x-4

When y=0,

-x-4=0
-x=4
x=-4
