SO I HAVE A QUESTION IS THE EQUATION Y-Y1=M(X-X1) AND Y=MX+B SAME GIVE EXAMPLES PL

Both of these are ways to express linear equations.

is the equation for a line with slope m which contains the point . This is called point-slope form.

is the equation for a line with slope m and y-intercept b. That is, it contains the point (0, b). This is called slope-intercept form.

Both of these are perfectly valid ways of writing lines, though sometimes one will be easier to use than the other.

the image of (6, 9) under a dilation is (4, 6). the scale factor is

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
