#y = 7/10x -8#

Explanation:

This is the easiest question we can get to find the equation of the line! The point we are given #(0, -8)# is the y-intercept (c). The clue for this is that the x-value is 0, which means the point lies on the y-axis.

#c = -8, and m = 7/10#

So, we have #c#, we have the slope #m# and we can just substitute the numbers into #y = mx +c#

#y = 7/10x -8#

#y=7/10x-8#

Explanation:

The equation of a line in #color(blue)"slope-intercept form" # is

#color(red)(|bar(ul(color(white)(a/a)color(black)(y=mx+b)color(white)(a/a)|)))#
where m represents the slope and b. the y-intercept.

here b = -8 and #m=7/10#

substitute these values into the equation.

#rArry=7/10x-8" is the equation"#
