Question

State the slope and a point on the line y - 18 = 71.3(x +98)

explain how you got your answer

Answer 1

The slope is 71.3 and the point on the line is (h, k): (-98, 18)

Explanation:

y - 18 = 71.3(x +98) is to be solved for the slope and a point on the line represented by this equation.

Refer to the point-slope formula y - k = m(x - h), where (h, k) is a point on the ine and m is the slope of the line.

Comparing y - 18 = 71.3(x +98) to

y - k = m(x - h),

we readily see that k = 18, h = -98 and m = 71.3

The slope is 71.3 and the point on the line is (h, k): (-98, 18)

Answer 2

slope = 71.3 and a point (0, 7005.4)

Explanation:

the slope in an equation of the form y = mx+b, m is the slope so multiply 71.3 through the brackets and then add 18 to both sides and that is the equation in y=mx+b format and 71.3 is the slope and b os the y-intercept which turns out b=7005.4 and since its a y-intercept x = 0
