Answer:

-1/3

Step-by-step explanation:

3 is the gradient of the other line

m1×m2=-1 (equation for perpendicular lines)

m1×3= -1

Find the equation of the line using the point-slope formula. Write the final equation using the slope-intercept form. the x-inte

wariber [46]

Step-by-step explanation:

Given x intercept is 1, So (x,y) is (1,0)

When x intercept is 1 then y value is 0

Another point on the line is (-2,3)

Two points are (1,0) and (-2,3)

Find out slope using the two given points

$slope m=\frac{y_{2}-y_1}{x_2-x_1} =\frac{3-0}{-2-1} =-1\\m=-1$

Use point slope formula

m=-1 and point(1,0)

$y-y_{1}=m(x-x_{1})\\y-0=-1(x-1)\\y=-1x+1$

Point slope equation is

$y-0=-1(x-1)$

Equation of the line in slope intercept form is

$y=-1x+1$

iVinArrow [24]

Answer:

x=11

Step-by-step explanation:

(7x+14)=(9x-8)

7x-9x=-14-8

-2x=-22

-2x/-2=-22/-2

x=11
